Application of micro-course video in optical manufacturing technology

Abstract

Optical Manufacturing Technology is a compulsory course for postgraduate and advanced undergraduate majors in optical engineering and similar majors. Modern fabrication and testing equipment are extremely expensive, which cost millions or even tens of millions, and having high requirements for the use environment. Most schools that do not focus on optical fabrication rarely purchase these devices for educational purposes only. Relevant professional teachers are also not familiar with the working principle and use process of the new fabrication and testing equipment such as Computer Controlled Optical Surfacing (CCOS), Magnetorheological Finishing (MRF), Ion Beam Figuring (IBF), laser tracker and LuphoScan interferometer. This has caused the teaching content of the course to stay at the stage of singleaxis machining, knife-edge tester, so that students' knowledge of modern equipment is almost blank. While teaching with micro-course videos, the relevant equipment use process can be visually presented to students, and relevant technical experts can also explain the working principle and scope of application to students more professionally. According to the survey, 82% of students like this micro-course video teaching, acknowledging that it helps to better understanding modern optical fabrication and testing equipment, expand students' knowledge, and increase students' advantages in employment competition.
