BF109 - Can't we just have the gunsight in the middle?

Why not?

1: You're sat in a 109.

2: Looking straight ahead.

3: Both eyes open.

4: Revi offset to project the reticle image directly into your right eye only.

I submit your view would be more or less like this..... (paintshop skills notwithstanding)



What would you see?

try it yourself, Lixma.

Go to a mirror (the reflector glas is nothing different that a transparent mirror) and see if you can see anything from behind you at the side of the mirror. I guess you won't see anything exept the wall to which the mirror is attached.

we understand what you're trying to say Stormcrow, but the old "arcade machine" type reflection system has the source a lot closer than the bathroom wall.

That still cannot defy physical laws. The distance between the light source and the reflecting surface is irrelevant to optical law. Only the angles count. See my previous post one page before.

source distance to reflector makes a big difference, Stormcrow. You only get the big shift when the source is a big distance away

Gun Cam Harmoniser (Pg 1 Gun)... illustrates my point

its about 1/5 the way down the page

First you won't need a big shift in the 109. And I would also say that the required shift is by far less than in the image you're pointing me to. IF distance of the light source is significant at all which I still doubt. The limiting factor is the size of the reflector glas, not the distance. The distance only plays a role because of optical size reduction with increased distance. But this factor is irrelevant for a particularly designed light image projected actively at a certain angle on the reflector surface.

EDIT: Also reflector surface sideway inclination plays a role (see last picture in my post)

I liked the revi behaviour in the old sturmo adn get used to it. It was good to have the same FoW with Shfit+1. A track IR device costs 1/4 of my earnings in a month, so i'm a bit sad about this also

you'll have to take that up with the real world image, Stormcrow

the critical distance is if the left edge of the reflector glass is central to the position of the human nose & the nose of the aircraft, if it is then is the distance from the left edge of the reflector glass to the centre of the reflector glass the same distance as the human anatomy from the centre of the human nose to the centre of the right eye.

if yes to all the above then the right eye is in perfect line with the centre of the reflector glass thus reflector light and the brain will naturally merge the left/right eye image in the same manner to if you were to use a marker pen on a bit of clear glass to mark a X and with both eyes open were to position it in line close the right eye, however with respect to the gun sight and the above there needs to be a narrow angle of view for the “reflective recticel” so it cannot be seen at all by the left eye when the right eye is positioned correctly.

Can you make a drawing? I really don't get what you try to explain, b101.
