Course objectives and basic requirements:
This course instructs the students in fundamental technical knowledge and training, so as to improve their technical background and engineering skills. In this course students will learn the imaging concepts and characteristics of simple optical systems, theories of Gaussian optics, light diaphragm and fundamentals of photometry, principles of classical optical systems and theories of aberrations. After the course the students can design Gaussian parameters of optical systems, and do some basic optical experiments.
Course introduction:
The course comprises the primary parts of geometrical optics, classical optical systems and aberration theories. The geometrical optics covers the contents of imaging concepts, principles of Gaussian optics, optical energy and light diaphragm. In the part of classical optical systems, the imaging characteristics of eyes, microscopes, telescopes, photographic systems and project systems are discussed. Aberration theories are described in detail, including their concepts, definition, primary feature and correction. This course gives the students a good foundation for leaning optical system design.
