Fundamentals of optical engineering is a very important basic course for optoelectronics and instrument majors, and is one of the " housekeeping courses " for undergraduates in related majors . The basic course of optical engineering is divided into two parts: applied optics and physical optics. Applied optics mainly includes three parts: ideal optical system, ray tracing and imaging quality, and optical system. Physical optics mainly includes five parts: electromagnetic theory basis of light, interference optical system, diffractive optical system, crystal optics basis and Fourier optics. This course provides students with a solid foundation and rich applications. We are confident that you can understand the wonders of the optical world.
