Paper Abstract

A drive electronics system for a biocular helmet-mounted display (HMD) is described. The system features microprocessor control with a 1553 interface, raster and stroke graphics multiplexing, image space stabilization, and compensation for pilot head roll. This paper details several video processing functions that have been implemented with mixed-mode integrated circuits including video channel selection and amplification, sync separation, sweep ramp generation, raster and stroke graphics multiplexing, and image space stabilization. Improvements due to use of integrated circuit technology include: circuit card area reduction by a factor of three, power consumption reduction by a factor of four, and an increase in circuit functionality of approximately 50percent.
