A high power, narrow linewidth single frequency laser diode as one of the key elements of Integrated Optical Rotation Sensor (IORS) is studied.
对谐振式集成光学角速率传感器IORS的关键器件之一——大功率、窄线宽光源进行了分析与实验。
The camera works by illuminating objects with a laser that emits a different infrared frequency for every single pixel, allowing them to custom-amplify a signal that would otherwise be too dim to see.
该相机的工作原理是：用一束激光照在物体上，每一个像素点都被不同红外频率的激光照着，以此来优化放大在其他情况下太弱而看不见的信号。
A method using the frequency divtion multiplexing technique of the laser speckle's spatial frequency to record multiple displacement information on a single specklegram is presented.
利用激光散斑空间频率的频分多路传输技术，能够在一张散斑图上记录物体多次变形的全场位移信息。
