Course Category: major course of subject.

Period/Credits: 32/2

Prerequisite: Applied Optics, Physical Optics, Optical Detection, Photoelectric Technology Foundation, Optical Part Technology, Digital Image Processing, Error Theory and Data Processing, and so on.

Aim & Requirement:

The course is the major course for all students for PhD degree in optical engineering. It is necessary for the students who want to performance some related optical testing. The main objects are the students whose majors are optical engineering, also the students whose major are not optical engineering can choose this course. Through the course students can get the systematic training and general knowledge in modern optical testing technology. The course content contains modern optical testing technologies based on the different theories such as interference, diffraction, holographic, optical scanning, light speckle, Moire technique, light spectrum.
