ABSTRACT:
A cathode ray tube is used to address a spatial light modulator. The light used to read the spatial light modulator is preferably passed through an acoustic optical tunable filter to enable the wavelength and intensity to be rapidly controlled to provide, for example, a multicolor display of variable intensity. This finds particular application in head-up displays for use by pilots of aircrafts.
