Ser. No. 001
An early demonstrator in 1978 was this ‘Lensless HUD’ This design uses a TV Monitor projecting into a three element Combiner which carries out collimation with no further lens groups. This is Serial No.001 although it is the only one of this type made. The lower picture is taken from a FARL Research paper shows a two element prototype of the design and presumably predates the three element version. A slightly earlier version used a Cathode Ray Tube in place of the TV Monitor.
With the eventual addition of a relay lens this design was to be developed into the DHUD or LANTIRN HUD.
