NVG Issues in VR

[blunt_waco]

Why is NVG looks bad in my VR? Do you guys have the same grainy quality issue! I had to alternate between turning NVG on/off for flying and Shkval.

 

 

Here is a video I recorded today.

I can confirm.

The Ka-50 NVG is like this

You have to become very proficient with those 3 tumbwheels and all the other cockpit light's dimmers

That's not an issue. NVGs are like that, although they're green, not b&w (who knows, the Russians may have had a b&w model, , but the grainy slightly out of focus look is correct

 

The following images are from an NSP-3, a Russian night vision rifle scope

Check this video at 10:40. Why his is clear and different?

[flanker0ne]

Because that night itsn't very night

The color depends on the phosphor used inside the tubes. As an example, most newer western NVG's have switched to a white phosphor which gives a black and whit look instead of the green. My current AN/AVS-9s are white phosphor, for example. Somewhere online is a list of the various phosphor colors that have been used by various manufacturers over the years.

Huge difference though, grainy vs clear!!

Also, check the cockpit texture in NVG between the two videos, mine and the YouTube.

Hm, I fly in VR so we get the whole FOV showing up as NVG, instead of the TP tube (Which is more realistic since you can look under/around your nods to see your pit).

 

Bur I don't recall it being grainy.

Correct.

 

P20, Green phosphors were originally used because the human eye is most sensitive to green colors. Also most green phosphors had a longer persistence time, and were therefore "brighter" when the early gen2 nods came out. From all I heard the very early experimentation with PVS-5's adapted for aviation use were very scary to use.

 

Probably the most common phosphor used with ANVIS was the P43 yellow/green phosphors though some early ones were P20. P43 has a lower persistence time, which limited issues with streaking for aviation use. Plus Anvis was gen3 so had more electrons to work with than the earlier Gen2 goggles.

 

These days White phospors are used because they look more "natural" to the human eye and also have low persistence.

 

Most Russian gear I have is either a P20, or P43 phosphor to include 80's era Mi-24 aviation goggles (Which are hot garbage btw as they are effectively gen0 and need to be used with a fairly strong IR source).

Yeah, however fortunately there are no gen1 cascade systems used for goggle applications, its either Gen0, Gen2 or Gen3 tubes which lack the geometric distortion seen in Gen1 triple cascade systems.

Can anyone fire up a quick mission and test NVG in KA50?

Yep. They started out just using the basic 5s with that face covering, which they called "full face fives". That didn't last long because it basically meant that one guy had to fly on goggles and the other guy had to watch the cockpit instruments. So they started just cutting out the facemask part so they could see under the tubes. It didn't help that the 5s were crap to begin with, at least for flying. It's amazing how far we've come.

Yeah, I've got mostly a full collection of functional aviation gogs at this point, everything from the various chop mods, to the COBB mounts, aside from helmets. The surprising thing is that the commercial gen2+ pvs-5 stuff from Litton in the late 80's was dramatically better, basically equivalent to early 90's gen3 anvis.
