Click For Summary
The discussion centers on the challenges of achieving collimation from an LCD display for use in a heads-up display (HUD). Users explore whether a lens should be placed in front of the display or if a collimated light source is necessary to achieve a clear, collimated image. Various methods for collimating the image are discussed, including the use of Fresnel lenses and the potential need to keep certain optical layers intact for optimal brightness. Participants also share personal experiences with modifying displays and light sources, highlighting the importance of precise distance and lens choice. The conversation emphasizes the technical complexities involved in creating a functional collimated HUD system.

Hello Anorlunda,
I took a look at the 'Spyglass' Android app. Looks interesting in it's own right. Not quite what I'm looking at, but interesting never the less.

The use case is actually for tracking sailboats in a sailboat race. Each of the racers will be carrying a small gps tracker that relays their position amongst other info. This is relayed and processed and then basic facts relayed to the binocular HUD/AR device. The device includes a gyro and compass for binocular orientation.
Why not just use hull numbers or names (I'm not sure how sailboats are labeled -- whatever is equivalent to tail numbers for aircraft)? How do you plan to handle sailboats that are side-by-side and so in the same line of sight from your location?

Working on a physical binocular attachment at the moment that includes the lens system. This bit is the *most* challenging :-)
Are you able to open up the binoculars to add your optics inside, or are you trying to do this all external to the binocs? If all external, maybe use something like Google Glass or similar HUD glasses, rather than trying to add something to the front entrance of the binocs?
