- Instrument Introduction
The SGY-5 Photoelectric Direction-Finding Experiment Apparatus uses a laser as the light source and a quadrant detector as the photoelectric detection receiver. Based on the principles of electronics and differential measurement, it provides a photoelectric direction-finding device capable of intuitively and rapidly observing, locating, and tracking the direction of a target. It is currently one of the most widely used methods of photoelectric direction-finding.
