What is the thing that looks like a laser dot in the NVG?

[counter25]

Hey!

 

I noticed that there is a moving point looking like a laser point in my NVG, which moves together with the targeting optics (but the opposite way :S). What is it?

 

Thanks!

Well, that the laser telemetry. Very useful to point a target to your wingman at night. I still don't understand why it moves laterally the opposite way of the ministick. Bug?

Thanks a lot! :)

Hrm, is that realistic? I mean, laser designators are invisible in NVGs, afaik. And laser range finder would have similar requirements (signal strength, etc.?) as a designator ... so I would assume, laser range finders should also be not visible in NVGs?

Also, not really helicopter related but LRF through NVG on a rifle (check at 0:44):

You can see the range finder with NVGs??? Must test this!

 

Also from my US Army infantry experience, many laser range finders that use infrared is usually visible in some form under NVG- and some non-infared ones that would otherwise be hard to see with regular eye are visible in some form. I've often wondered if the Gazelles ranging laser should look like the A-10Cs or MQ Predators. Seen those in real life and it's awesome. Where the Gazelle is concerned is if the range device is infrared, and to that I do not know the answer

The Nd:YAG lasers commonly used for range finders and designators have an emmision wavelength of 1064nm, which is close enough to the visible spectrum that light amplifying NVGs usually are able to detect the laser.

Makes since! That's why I've probably seen as much using gear like the PVNS 14s with the Army

I come back from a multi-crew flight and we had that light point with NVG too. Funny at the beginning but annoying at the end...

Looks like it triggers the Ka50 Rwr when you are aiming at your wingman in MP. Funny.

Annoying - in which way? Isn't it only visible if the range finding laser is active for a few seconds?

[BaD CrC]

No,it's visible all the time. But i dom't think it is annoyimg. And it looks realistic.

[Flagrum]

Hrm. Always visible ..? That rather sounds like a bug then. Why would you want lase all the time? Especially if, as you said, laser warning receivers will pick it up as well. Just makes no sense, imo.

 

@Polychop - could you chime in here please? Bug? Feature (with what reasoning)?

Ka-50 has a laser warning receiver, not radar. So a rangefinding laser probably should trigger it, although only when it's active of course.

[BaD CrC]

yes. Sorry I meant lwr, not rwr.

Probably because of the way the sight is coded. We'll see if Poly is able to suppress this. Not sure as long as it may be part of the basic code.

Up for this topic. This laser pointer still laterally moves opposite to the camera movement, i.e when I move the sight left, the pointer goes right and vice versa. The up/down movements are fine though.
