-Instrument Introduction

The SGY-5 photoelectric orientation experimental instrument uses a laser as the light source and a four quadrant detector as the photoelectric detection receiver. Based on the principle of electronic sum difference, it realizes a photoelectric orientation device that can intuitively and quickly observe, locate, and track the target orientation. It is currently a widely used photoelectric orientation method.
