Paper Abstract

In the simultaneous measurement of the sagittal and tangential modulation transfer function (MTF) of an optical system by using a square object, we analyze various correction factors due to the irregular illumination of the source, the rotation of the square object, and the off-axis effect by the object size for the precise measurement of the MTF. These results can be used in the more exact and effective MTF measurement using the square objects instead of an ordinary pinhole or slit.
