| Abstract: | For acquiring proper exposure aerial photographs in wide brightness of scenery, a wide range adjust light system is designed for a new type aerial camera. A wide range programmed adjust light method of auto controlling the diaphragm and shutter speed is presented. The basic configuration and principel of programmed adjust light are introduced. The hardware theoretic electric circuit and the software design are showed for a programmed adjust light system. The system has wide adjust light range, accurate control, high reliability and runs steady in test and flight, which meets the requirements of aerial photo-reconnaissance. |
