Proceedings PaperSine Wave Testing And Its Practical Implications
|Format||Member Price||Non-Member Price|
The quality of image forming optics may be determined in a number of ways from the purely psychological to the purely physical viewpoint. Sine Wave Testing is a physical method which completely specifies the optical response of an instrument. There are a number of other physical methods which can be shown to be completely equivalent. They are compared both for usefulness, ease, and accuracy of measurement. The implication of these considerations for system design and practical quality control is reviewed with emphasis of the use of Sine Wave Testing.
