光学瞄准镜相对畸变测试技术研究

Research on the Relative Distortion of Optical Sighting Telescope

畸变是物体经光学系统成像后的实际像高与理想像高的差值,虽不影响成像的清晰度,但却影响像的真实程度,对于光学瞄具这样的高精度瞄准系统而言,其畸变的大小对整个系统的工作性能具有决定性的意义。文中介绍了光学瞄准镜相对畸变的测试原理及测试系统的组成。实验结果表明,系统的测量精度较高,达到了技术指标要求。

The distortion is the differencing between the actual and Gaussian image height,which donesn＇t affect the definition of image,but could affect the the true extent of the image.In terms of the high-precision sighting system as the optical sighting telescope,the size on the distortion has decisive significance for the performance of the system.Testing principle and the composition of relative distortion of the optical sighting telescope was introduced.The experimental result indicated that the testing accuracy of system was higher,and meet the required standard.
