GLGDT modern photoelectric characteristics comprehensive experimental platform 

Ⅰ、Overview

The GLGDT modern photoelectric characteristics comprehensive experimental platform is a multifunctional experimental system integrating light, machinery and electricity. The system covers a wide range of content and can conduct experiments on the principles, characteristics and performance parameters of various devices such as signal sources and photoelectric detectors used in optical communication, information control and photoelectric detection. It can also conduct a series of photoelectric experiments such as light transmission, application of photoelectric sensors, light intensity analysis and moiré fringe counting. The experimental platform uses a fully automatic monochromator to realize the continuous measurement of the spectral characteristics of photoelectric devices, and the experimental results are directly displayed in graphics on the computer; the CCD camera method is used to realize the automatic counting and micrometering of moiré fringes; the single-slit diffraction image is collected and processed by the CCD camera method to realize the two-dimensional and three-dimensional distribution display of diffracted light intensity. The system adopts a modular combination method, and different majors can have different menus. The system provides open circuits and optical paths, which lays the foundation for students to better understand and master the principles and correctly use photoelectric devices, so that students can learn to reasonably select sensors and master the principles and methods of detection through experiments. It is suitable for teaching experiments in optoelectronic information majors, electronic information majors, metrology and testing majors, etc.
