VS212A Optics and Dioptrics of the Eye
Coursemaster: Austin Roorda, PhD, Minor Hall rm 485, 510-642-2380, aroorda@berkeley.edu
NOTE: This course is now administered through bCourses. I will only update the lecture notes here for thos who are unable to register for the class.
Abstract:
The purpose of this proseminar is to give an overview of optics, optics of the eye, how the optics of the eye affect instruments that measure ocular properties and how the optics of the eye impact vision. The lecture will span basic geometrical optics of the eye, physical optics and finish with discussions of current visual optics research. There is a lab component of the course which will give you hands on access to an optical system designed for vision science applications and will give you an opportunity to do some data analysis.

Organizational Meeting (possible changes to schedule)
(time perimitting) Basic Optics Nature of Light Spectra Refraction Image formation Ray tracing Thick lenses and Cardinal points Lateral magnification Optical systems
|
This text … Keating MP. Geometric, physical and visual optics. Boston: Butterworth-Heinemann, 1998 …is a decent reference to help you with the basics. It is not required that you read it, but you might refer to it for more thorough explanations of some of the concepts.
My favorite optics text is.. Freeman MH. Optics. London: Butterworths, 1990 (on reserve in library) …just be careful about the differences in syntax between this and Keating. I use the syntax from Freeman. |
