Reversed Binoviewer

[Robindonne]

Was wondering if someone ever tried a binoviewer (attached to a binoscope) in reversed position. And center the two outputs to one image

Probably someone has but not worth doing seriously, you would lose the benefits normally obtained by binoviewing.

Hm yes thats what i was wondering.  You split/dim the light for each eye when using a bino on a single scope. But when using a bino reversed on a bino setup you should think it shows a great contrast image. Or hard to get the two images aligned?

I don't think it would work.

It is easy to split light - but not as easy to "join" light.

Just try to make diagram with some sort of mirrors prisms - put two objective lens next to each other and try to bring rays to the same focus - here is example to see why it won't work:

You can't make element that takes light coming from the left and direct it downwards and at the same time take light coming from the right and direct it also downwards. One of them will have to go upwards.

If you try to bring them to the same focus at an angle - you'll just "warp" the image in focal plane - and warp it differently so it will not align even if warped.

In fact - when you think about it - what you want to do is called aperture synthesis and is used with radio telescopes. In such systems you need to be able to sense phase of wave and based on that synthesize final image. It can be done with sophisticated equipment at longer wavelengths - and you still need plenty of "observation" at different points in order to reconstruct the image - you can't do it in real time and it certainly won't work for visual light.

Yes i see all the impossibilities now.😬.  Really stupid idea.
