自动校炮技术对于实现坦克火炮校炮过程的自动化、智能化和提升射击精度具有重要意义，提出一种基于PSD（位置灵敏探测器）的光电自动校炮装置, 该装置以PSD为光电探测器件, 采用光电转换和信号处理技术, 实时自动获取坦克炮口弯曲变形量并给出火炮射击的修正量, 实现误差修正和车内自动校炮。该装置在不同初始位置和不同射角下，可达到0.1 mil(mil,炮兵测距用的角度单位，1 mil=0.060.001 rad)的修正精度。

Artillery auto-correction technique is important for realizing the automation and intellectualization of tank cannon artillery correction process as well as enhancing the accuracy of firing. A device for photoelectric auto-correction of artillery based on position sensitive detector (PSD) was introduced. By adopting PSD as the photoelectric detector and utilizing the photoelectric conversion and signal processing technology, this device could gain the real-time barrel bending deformation automatically and give the correction of the howitzer, so as to realize the error correction and the automatic correction in the artillery. At different initial positions and shooting angles, the device could achieve the correction precision of 0.1 mil (mil :unit of angle for artillery measuring distance, 1 mil=0.060.001 rad)
