Paper Abstract

In many methods to measure the Modulation Transfer Function( MTF ) of an optical system, a pinhole or a slit is used as a test target. In such methods, the light flux that is diverging from a test target must illuminate the full aperture of the test lens evenly. In practice, however, it is rare to satisfy this condition especially for a measurement of an optical system of high numerical aperture. And the insufficient illumination causes some amount of error on the measured MTF values. This paper describes a method for estimating the error of MTF values that are caused by the difference of illumination condition.
