Paper Abstract

The optical transfer function(OTF), or more frequently the modulation transfer function(MTF) has been used to evaluate the image quality of lens and optical systems as a objective criteria. But practical aspect of lens testing to evaluate a prototype optical system we must measure many MTF curves for several conditions such as image heights, focus positions and F-stops. In previously developed instruments, it is time consuming to make the MTF measurement and it is troublesome to rewrite the original data for desired correct MTF curves after measurement.
