光电定向实验应用平台的设计

The design of the photoelectric orientation experimental application platform

光电定向是指用光学系统来测定目标的方位，在实际应用中具有精度高、价格低、便于自动控制和操作方便的特点。因此在光电准直、光电自动跟踪、光电制导和光电测距等各个技术领域得到了广泛的应用。本实验平台采用激光器作为光源．四象限探测器作为光电探测接收器，根据电子和差式原理。实现可以直观、快速观测定位跟踪目标方位的光电定向装置。

Photoelectric orientation refers to detecting the position and orientation of target by using optical system. This measurement method can be controlled automatically and operated conveniently with high accuracy and low-cost. Photoelectric orientation has been widely used in the applications of collimation, automatic tracking, guidance and ranging. Here, an experimental platform of photoelectric orientation is designed based on the electronic circuit and differential theory with laser as light source and quadrant photodiode as detector. The device use laser as light source and quadrant photodiode as detector, and can detect the position and orientation of target simply and quickly.
