为了检测某型导弹激光发射机光轴同可见光观瞄镜小视场光轴之间的平行性,同时测量激光发射机主、次、小三个视场的光斑直径,设计了一种新的激光发射机光轴检测仪。它以硫酸钡漫发射涂料作为激光性能测试屏的表面,使光斑在屏上成像更加清晰;用模块化的激光光轴检测器提供系统工作电源和控制信号,并对CCD摄像机采集到的光斑图像进行压缩传输。最后,通过Lab VIEW视觉处理模块对光斑图像预处理并用Matlab编定的圆拟合算法程序计算激光光斑中心位置和半径值。实践应用表明,该检测仪能精确高效地完成激光发射机光轴检测任务,便于部队机动、携行。
In order to detect the parallelism between the optical axis of a missile laser transmitter and the small field of view of a visible light sighting mirror and to measure the spot diameter of the primary, secondary and tertiary fields of laser transmitters simultaneously, a new laser emission Optical axis detector. It uses barium sulfate diffuse coating as the surface of the laser performance test screen to make the spot image clearer on the screen. The modular laser optical axis detector is used to provide the system power and control signals. The spot image collected by the CCD camera Compression transmission. Finally, through the Lab VIEW vision processing module, the spot image preprocessing and the circle fitting algorithm programmed by Matlab were used to calculate the laser spot central position and radius. Practice shows that the detector can accurately and efficiently complete the optical transmitter laser axis detection tasks, to facilitate the troops maneuvering, carrying.
