The Cross Hair on Gun Sight

[chisel]

OK,

 I talked to some guys on the LW newsgroup.
I was informed that there is a display setup in the Nat. Air and Space Museum in the US with German,British and American Reflector sights that are powered and you can look thru.

He said if you moved your LOS the reticule faded out.

If it works a different way Please explain "how" to me because I cant picture it (Honest requset no sarcasm is meant)

What a chance to plug the next CD - Aerial Gunnery... This page is way reduced in size  and converted to black & white. The real ones are at 300 dpi and most all are in color...

Here is the proof but not the explanation...

 

I'll put up a notice on the web site when this one is ready -  http://www.OldManuals.Com

chisel,

If you have a small mirror, please try this.

1.Draw very small circle on a piece of paper.This is your rectile.
2.Put the paper on your desk and place a mirror slanted (45deg.) on it.
3.See your reticle reflected throgh the mirror and move your head.

Dose the reticle seem to fix on the mirror?

OK, this is not exactly same as OPL because there is no lens between mirror and the reticle. But at least you can see the reticle slides on the glass.

If you have a lens and place reticle at focus point of the lens, you will see the reticle slides on the mirror with your head shifts and it is fixed related to infinity far point.
   
##How about this question?

How can you fix the reflected image of reticle on your sight glass(mirror)?
This is far more difficult.


Sorry about my poor English writing.    
Thanks.

With your head shifts, cross hair might fade, (especialy with point light souce) and also slides on the glass.

My friend who has K-14 gyro computing sight, said "The cross can be seen only from straight aligned point because it is so dark due to its rusted mirror"

But that doesn't prove anything about cross hair slide or fixed.

With proper "frost" bulb and clean mirror, I belive reticle will not fade so quickly with your head shifts.

Thanks
