Abstract

Since their introduction more than forty years ago by BAE Systems, Head up Displays have relied on the Cathode Ray Tube as their image source. The progression of electronic technology in recent years has prompted the search for an alternative to the tube as the primary image source. Until very recently, this work has centred on the Liquid Crystal Display (LCD). These are relatively inefficient devices, whether they be transmissive or reflective and this low efficiency therefore requires a very intense source of light to illuminate them. The difficulty of packaging, achieving a high reliability and a long life seemed to limit the application of the Laser as the illumination source. However with an innovative Laser illuminator working with the highly efficient DMD the author describes a 'next generation' HUD (Head Up Display) design.
