Aeroscout Posted April 19, 2007 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. DCS Wishlist: 1) FIX THE DAMN RIVERS!!! 2) Spherical or cylindrical panorama view projection. 3) Enhanced input options (action upon button release, etc). 4) Aircraft flight parameter dump upon exit (stick posn, attitude, rates, accel, control volume, control-surface positions, SAS bias, etc). 5) ADS-33 maneuver courses as static objects. 6) Exposed API or exports of trim position and stick force for custom controllers. 7) Select auto multiple audio devices
ED Team Groove Posted April 19, 2007 ED Team 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
Aeroscout Posted April 19, 2007 Author 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 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. A flight sim application: http://www.rickleephoto.com/rlcoll.htm -SK
thesystem Posted April 19, 2007 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
Pilotasso Posted April 19, 2007 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. I wish you good luck. .
Aeroscout Posted April 19, 2007 Author 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 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

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
