-Instrument Introduction

The SGY-14 PSD sensor experimental instrument uses an analog circuit to measure the center position of the light spot based on the current output from the two poles of the sensor, which is then converted into current and voltage by an operational amplifier, and subjected to addition and subtraction operations.
