| Abstract: | The Photoelectric position sensitiva device (PSD) with a novel PIN structure is mainly used in the auto-focusing system of miniature cameras, the operating principle and the distance-measuring method of the PSD devices are presented.Some improvements on structure and techniques were made in order to obtain high reverve breakdown voltage, high surface resistance between the two electrodes and high infrated sensitivity. The test results are consistent with those as requied. |
