Description

Technical field [0001] The invention belongs to the field of measurement control, in particular an innovative experimental platform for online measurement and control teaching based on optical detection, mechanical control, and electronic information. Background technique [0002] Traditional lithium battery film thickness measurement uses such as manual measurement, radiographic and ultrasonic measurement, while the detection of film surface defects often uses manual visual inspection. Because laser sensors and CCD sensors are non-contact measurement, small size, easy integration, low installation environment requirements, no safety protection measures, high measurement accuracy and online real-time measurement, they have become the mainstream of film thickness and surface defect detection. The innovative experimental platform for the online measurement and control teaching of opto-electronics is based on the principle of laser sensor triangulation and CCD digital image processi...

Problems solved by technology

[0003] In recent years, with the gradual rise of optoelectronic research and optoelectronic majors, optoelectronic-related professional courses such as signal analysis and processing, engineering optics, error theory and data processing, control engineering, sensor principles and applications, electromechanical detection technology, computer control technology, Due to the complex theory, strong practicality, limited practice time and single practice platform, students lack perceptual knowledge and it is difficult to understand the theory of measurement and control instrument technology, photoelectric test technology, automatic detection technology, photoelectric display technology and machine vision technology. The theoretical knowledge taught cannot integrate the above-mentioned professional knowledge as a whole
