- W1983202386 abstract "Various techniques are currently used to project video images. One of these, described in a previous paper by the author, operates by mechanical scanning of a laser beam with acousto- optic modulation, and has been proven suitable for high definition television and computer display scan rates by use of novel electronic and optical compensation methods. The requirement for improved image intensity with greater efficiency has led to a re-appraisal of the selection of the light source and the relationship between the light source, the form of the modulator, and the method of scanning. The electrical input to visible radiation output ratio of the Argon-ion lasers currently used in the projector shows efficiency to be as low as 0.001%, a factor limiting the commercial exploitation of the projector. Recent developments in acousto- optics can be applied to the projector's optical system allowing alternative light sources to be used. These help to reduce the complexity of both the optical and signal processing stages as well as improve efficiency." @default.
