Common Module Electro Optical Multiplexer Development.

摘要

The output imagery of parallel scan, modular FLIR systems is commonly viewed through an ocular or biocular eyepiece. For system applications requiring serial video for remote imagery or automatic tracking, parallel to serial multiplexing is required. A militarized 1 in. silicon television camera compatible with projected modular systems has been developed with extensive use of hybrid circuitry. The camera weight and volume are reduced to 2.0 Kg and 1600 cu. cm. and the total required input power is less than 8 watts to minimize the internal temperature rise and power source requirements. Automatic black level and gain control circuitry are provided, thereby insuring that the darkest and lightest scene elements are displayed at full contast. Camera outputs are EIA Standard RS-343-A composite video, unregulated non-composite video and vertical sync. The unregulated video is suitable for external generation of IR level and gain control signals and the vertical sync pulse useful for camera/IR scanner synchronization. Performance and test data are discussed and design features are highlighted. (Author)
