optical quadrant

基本解释

This paper presents a new optical system used for quadrant detection, in which point detectors, rather than area detectors, can be used.
本文提出一种新型的用于四象限探测的光学系统，该系统可以用点探测器代替面探测器。
At the same time optical rotation of the particles was realized. The rotation frequency was measured by CCD camera and quadrant photodiode detector (QD).
同时利用CCD相机和四像限探测器（QD）测量了粒子光致旋转的转动频率，研究了粒子的旋转频率随激光功率的变化关系。
An optical system is designed, which is based on the principle of double optical paths and according to the characteristics of four quadrant infrared detector.
针对四象限红外探测器的特点，设计了基于双光路替换法的光学系统。
