ABSTRACT:
An evaluation method for evaluating optical characteristics of an optical system, the evaluation method includes: providing an optical system that is an evaluation object and that has a light incidence section and a light emission section; disposing a first pattern having a fist predetermined pitch, in an optical path of light which is incident onto the light incidence section; disposing a projection surface having a second pattern with a second predetermined pitch, at the position to which the light emitted from the light emission section is reached; projecting an image of the first pattern onto the projection surface through the optical system; and evaluating the optical characteristics of the optical system by observing a state of moiré fringes which are generated onto the projection surface due to interference between the image and the second pattern.
