Title：Computer aided optical system design
Class Hours/Week: 1 - 3 Credit：2.5
Category：Specialty
Prerequisites：Applied optics, Physical optics
Audience：Undergraduates
Teaching manner：Classroom instruction and practice project
Course objectives and basic requirements:
This course aims to improve the overall capabilities of the students in using the fundamental theories to solve the engineering problem. In this course the students will learn computer aided optical system design, calculate the Gaussian parameters and determine the best initial structure for optical system design, learn the algorithm of ray tracing, the quality evaluation of imaging optical systems and non-imaging optical systems and their improvement. The students will also develop simple ray trace codes and complete design projects using the common commercial lens design software.
Course introduction:
The content of this course covers the fundamental theories of optical system design, the classic optical system, aberration theories, design a classic optical system using the commercial lens design software Zemax, writing of final report, including the drawings and design results; simulation of various complicated optical system using the non-sequence ray tracing method, build the optical model using ASAP.
