MXY8000-5 Four Quadrant Detector and Optoelectronic Orientation Experiment Instrument

1、 Instrument Introduction

This instrument uses an optical system to determine the orientation of the target, and has the characteristics of high accuracy, fast response, low price, easy automatic control, and convenient operation in practical applications. Therefore, it has been widely applied in various fields such as optoelectronic collimation, optoelectronic guidance, and optoelectronic ranging. In addition to allowing students to understand and master the principles and characteristics of four quadrant photoelectric sensors, this product also offers experiments on the practical application of four quadrant photoelectric sensors, such as photoelectric ranging, intelligent car obstacle avoidance, photoelectric position detection, etc., enabling students to learn and master four quadrant photoelectric sensors from shallow to deep, so as to independently design and complete projects in photoelectric ranging, photoelectric orientation, and other aspects.
