ABSTRACT
A test system based on Modulation Transfer Function (MTF) was developed and a systematic theoretical MTF measurement approach is introduced to measure the quality of imaging systems. The test system is composed of 6 different optics, illumination module, 2 different CCD cameras, a 1951 USAF resolution test target, fine positioning stages and the data processing software developed under MATLAB to calculate the image contrast at various spatial frequencies and to plot the MTF graphs. Results are presented using 8 different light sources for the 4 different lenses and their 6 different combinations: Rodenstock Apo Rodagon D 2x (Retro) with 1.6x extension tube, Sill Optics Correctal TL72/1.5 Telecentric Lens, Navitar Zoom 6000 motorized lens with 0.75x and none lens attachments and 2x-F mount
