Novosibirsk "defense" patented a fundamentally new laser fuse for missiles

The developers of the Scientific-Research Institute of Electronic Instruments, OJSC, have patented a new non-contact laser fuse for rockets and shells.

Laser proximity fuses are installed on many air-to-air missiles. The main problem with their application - ensuring resistance to interference, including to bright sunlight.

“Our specialists have solved the task set by the customer,” Valery Edvabnik, Deputy General Director of the Research Institute for Development, told Itar-Tass. arming the leading world powers. "

Fundamentally new fuse patented after a series of successful tests. The Institute has already concluded agreements for the supply of products for the assembly of systems adopted by the Russian army.

The company emphasizes that they are ready to fulfill the order for the production of the fuse in almost any volume that the Ministry of Defense of Russia will establish.

Anyway. Novosibirsk is one of the scientific centers working on defense since the days of the USSR. But Skolkovo is just a testing ground for breakthrough ideas, and when there will be returns, it is not known, although there are already some progress. But when the child grows up, then we will evaluate, but for now it’s too early to compare with someone.

Darling, let me kiss you !!!

In Novosibirsk, we have such specialists where Skolkovo got to, from the 80s on, he electronically fired rockets and torpedoes in the laboratory behind seven fences, the zone was not guarded like that. The truth then did not know what it is. Although we were not developers, although we were in a research institute and in Moscow in our city, but just specialists, though young after high schools, are all out of the ordinary, we liked this unknownness in special dressing gowns of a specific coloring and the pilot cap was obliged colors, not uniform of course, but beautiful with an embroidered emblem. The team has been doing it for 22-30 years, why don’t you do it, what have you been up to, I remember, it takes envy for the years spent in this enterprise for nothing, but five thousand in total. Football, volleyball, skiing, vodka, girls ... Right now, would it be for our youth ?! And maybe right now it is, we just old people understand it differently, let the youth also enjoy, work tirelessly and be happy with the results of their work!

Since the 80th year, the electronic stuffing of rockets and torpedoes in the laboratory has been run over seven fences, the zone was not guarded like that.

I had to go to work in this research institute. On my first visit I even had to get acquainted with the work of the local security. And all that, when leaving the dining room, an extra corridor passed and ran into a guard. At once:
- Who is what you are doing here, give me a pass, a certificate of the admission form, a travel certificate, a passport, let’s go with me to the authorities!
The Vohrovites noticed, they began to sew business ... I had to attract the head of the department to which I arrived. Then we neighed on this subject.

Nah, we had it like that !!! We go through the pass to the factory entrance, in the 80th he had not yet recorded, only after a year or two.
I went to Kiev on a business trip np 2,60 rubles a day, it was enough, yo_myo., Sometimes you save money, ..., a_a I remember ... they sent us two (the kingdom to my friend) for simple batteries for the TANK, but this is not ours profile, but do not care, let's go, because to go to Riga, yeah, through Yshkar-ola (Shop-she, although no, I remember there in the hotel a chick for two brought ...) already Gorbach and lawlessness about vodka, well We quietly divided this madadama into two, equally divided, she remained a consonant (right now), but for general happiness ,,, she said: "it is better for ... one mind", Ooh, but there is no market, they threw them on the cards .. I went to the nearest cinema. I come, Zhenka says ... come in ...
The thing is, we were young and healthy, right now stupid and with a barrel almost in an embrace, cartridges, dope ..., kvkme fuck Muslims ..., yes, we only carry them out one and a half and a half together ... was .. .......

[Locksmith]

This is apparently an "antidote" to EMP, so that they cannot suppress the radio channel of the rocket fuse. Very well!

[KuigoroZHIK]

Not only.

And neither nature nor the modern armament of the leading world powers can prevent this.

- solar radiation (that is, bright sunlight) has a slightly different nature from EMP;)

[rolik]

Solar radiation is mentioned in relation to a photo-guided missile; it works poorly against the sun. With the new fuse, this problem is not.

[rolik]

EMP affects all electronics. If this happens, all electronics, including the receiving sender, will still fail. In this way, a new laser fuse, we get rid of the problems associated with the enemy's electronic warfare. That is, the rocket will not be deceived by a false target, including the crawler, but will explode next to the victim.

The principle of operation of a laser fuse is to assess the difference between the time of sending the laser pulse and the time of arrival of the pulse reflected from the target. Thus, the distance to the target is estimated. When this distance coincides with the set (usually 3-5 meters), the warhead is undermined.
The details of the use of semiconductor lasers in domestic military equipment were discussed at: http://lasers.org.ru/forum/threads/Military - application of semiconductor lasers

Laser fuse does not respond to false targets such as thermal missiles. For him, some big shit that had fallen off the plane could have been a false goal.

This has nothing to do with EMP. It is about protecting the photodetector of a laser fuse from exposure to solar radiation, which can bring it into saturation mode with loss of sensitivity. In this case, the laser fuse "goes blind".
The report does not say how this is done. Understood, secret.

[webdog]

Mamba, you think)))
you say everything right ... (in general)
the sun has a very long spectrum. almost without gaps ...
but some wavelengths (not related to visible) are greatly suppressed by the atmosphere.
therefore, in a given spectrum for a photodetector, the sun "does not shine" at all.
and the laser beam does not have to be in the visible spectrum. his task is to achieve the goal and reflect)))
therefore, the laser is tuned to the spectrum in which the sun "does not shine" in the atmosphere ...
it's just my speculation ... nothing more)))
I think so.

Here you are right, namesake.

Quote: webdog

It is truth too. But this applies to short-wave radiation: ultraviolet, x-ray and gamma radiation. The semiconductor lasers used in laser fuses operate in the near infrared range at wavelengths of 850-900 nm.

Quote: webdog

Here you are wrong. Shines in the IR range, and how! Modern photodetectors made of silicon or gallium arsenide are illuminated by the sun and go blind, regardless of the mode of operation of the laser (pulsed or continuous) or the mode of operation of the photodetector (gating or narrow-band filtering).

Quote: webdog

Of course, the near infrared is invisible.

Quote: webdog

Absolutely.

Quote: webdog

The laser itself does not tune and does not change the wavelength of its radiation. And the use of near-infrared lasers in fuses is due to the fact that the technology for their production is most developed. In the near future there will be industrial designs of semiconductor lasers operating at longer wavelengths: more than 10 microns. This is the range of transparency of the atmosphere. They can be used already on the battlefield in fog and dust.

Quote: webdog

Commendable. But not so simple. However...

[webdog]

yes this is just a great short lecture))) thank you, namesake ...
gained knowledge ... I love them)))
it means a laser in the IR range ... it goes without saying that the sun is in this spectrum of pechot! sunbathe my back)))
I think that the principle of the invention is based on the physical differences of refraction, absorption (attenuation) or interference of a laser beam compared to ordinary (non-coherent) radiation ...
using the differences you can separate the laser stream from the background ...
on this my operational knowledge ends))
I think so.

No applause. These are just a few short comments on your text.

We feel solar heat in the far IR region. These are wavelengths from 4 microns to 12 microns.

I think so.

Even if the laser fuse electronics is precisely tuned to the wavelength of the native laser, its pulse duration and the pulse repetition rate, and the photodetector works with a narrow-band polarizing light filter and is hard-gated, this will not protect it from sun exposure. The physical laws that you mention are the same for incoherent solar radiation and reflected from the target low-power laser pulse. The differences can only be said for the emitted powerful pulse relative to the background illumination.
I repeat, the namesake: it’s not so simple. Otherwise, everything would have been invented for a long time. Personally, I have no answer yet.

It has been invented for a long time ... now it is in demand

good news for aviation

On Saturday and Sunday I watched from my window from the fifth floor flights from Chkaldy Sukharei of the 34th (although they have been flying for the second week, but I have no time to see work), on Saturday we started closer to dinner, and on Sunday from in the morning, at 9 / 9-30 local time, they take off beautifully. The sky on Sunday cleared, far to see, but the plague immediately goes far, returning in about forty minutes. One, however, got out close, a couple of candles and a dive worked not far away (the runway from my house is 1,5-2 km) from me, I turned a few barrels at the exit, reluctantly, like such a homna as much as I like, then abruptly with a fast and furious and vertical candle meters on a thousand and went exactly into the horizon, with a coup with the approach to the strip ..., beautiful!

[demon ada]

for enemy aircraft is NOT very good news))))))
I would say that it is not very good.

And Skolkovo is just a testing ground for breakthrough ideas, and when the return will be unknown

It seems to me that Skolkovo is a testing ground for the development of the budget, first of all, and of course, a showcase of "modernization", although who knows, maybe I'm wrong - time will tell.
And the news is great.
