Aeroscout Posted April 19, 2007 Share Posted April 19, 2007 How does one get the light beams to focous into infinity so that the pilot can focous on both the HUD and what is outside the cockpit? I want to try to build my own model HUD to try to replicate this, (with out moving parts, just a solid, non moving, light beam) but this is quite difficult. Any info on how this is done would be much appreciated. If this is an impossibility for me to replicate, please say so, i wouldn't want to waste soo much time. however, please still post information on the focousing part.

ED Team Groove Posted April 19, 2007 ED Team Share Posted April 19, 2007 I dont think you can focus on two different visual ranges at the same time. Our Forum Rules: http://forums.eagle.ru/rules.php#en Link to comment Share on other sites More sharing options...
Aeroscout Posted April 19, 2007 Author Share Posted April 19, 2007 Then how does the HUD work? I'm almost sure you can..., so lond as the light is being focoused into "infinity" or what ever...

SwingKid Posted April 19, 2007 Share Posted April 19, 2007 It's called a "collimator" - basically a normal convex or flat Fresnel lens, with the subject being located at a certain focal distance.

thesystem Posted April 19, 2007 Share Posted April 19, 2007 i have seen some home made Huds. can;t find them right now but maby this is handy http://forums.frugalsworld.com/vbb/showthread.php?t=93328 DCS World, A10C, AV8B, M2k, FA18C, FC3, MIG21 Link to comment Share on other sites More sharing options...
Pilotasso Posted April 19, 2007 Share Posted April 19, 2007 Aeroscout as SK has hinted you may need high precision optics, thats not easy to come by, expensive and hard to design.

Aeroscout Posted April 19, 2007 Author Share Posted April 19, 2007 Is there something special about the glass. Is the RL HUD the same idea in the flight sim one in SwingKid's link?

pho3nix Posted April 20, 2007 Share Posted April 20, 2007 Aeroscout, most people seem to be confused about the definition of 'colimated'. A colimated light beam is one that has a constant spot size along any point of the beem, parallel if you will. Images in the far field, i.e. objects viewed from a large distance, approximate this criterion. The human eye operates via this method and 'auto-focuses' the image at 'infinity'. Therefore if you combine the collimated light beams from the HUD projector with those from out the front of the aircraft far away (such as a target) they will be in the same plane of focus and appear as one image. That is also the reason why when you move your head, the HUD image seems to be the same size and 'ground stabalised' i.e. self aligning as we can see in the BS movies. Hope that clears things up and does not confuse things further :p Link to comment Share on other sites More sharing options...

It should be possible to do, but here is a complete one...allthough it's not cheap. But it's just PnP with LockOn as well as Falcon :) http://www.simmeters.com/products.html Link to comment Share on other sites More sharing options...
