激光测距观察仪中光学薄膜的研究

Research on Optical Thin Film in Laser Range Finder

激光测距观察仪不仅能观察远距离目标,还能利用激光测距原理测出目标与观察者之间的距离。为了实现这两大功能,必须在激光测距观察仪的光学系统中制备大量的光学薄膜。根据光学薄膜的用途不同,光学系统中的光学薄膜主要有双波段增透膜、干涉截止滤光膜、可见光宽带增透膜和红外点增透膜等。

The laser range finder can not only observe a long-distance target, also make use of laser to measure to test the distance between target and observer. For carrying out these two greatest functions, have to make a great deal of optical thin film in the optical system of Laser range finder. According to the different use of optical thin film, the optical thin film in the optical system mainly has two wave-range antireflection coating, interference cut off filteration film,visible wideband antirefilective film, and infrared point antireflective film,etc.
