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.
本文提出一種新型的用於四象限探測的光學系統，該系統可以用點探測器代替麪探測器。
At the same time optical rotation of the particles was realized. The rotation frequency was measured by CCD camera and quadrant photodiode detector (QD).
同時利用CCD相機和四像限探測器（QD）測量了粒子光致鏇轉的轉動頻率，研究了粒子的鏇轉頻率隨激光功率的變化關系。
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.
針對四象限紅外探測器的特點，設計了基於雙光路替換法的光學系統。
