Paper Abstract

This paper will describe the instrumental details of a modulation transfer function analyzer capable of presenting automatically the MTF curves in the frequency range of : a) 0.4 cycles/mm to 10 cycles/ mm; b) 4 cycles/mm to 100 cycles/mm; and c) 24 cycles/mm to 600 cycles/mm. The instrument is designed to produce an MTF curve,after the optical element has been set in place, in approximately 5 seconds, with an accuracy of ±5 percent of the indicated response value. This instrument has been used extensively for testing of lens systems, fiber optics components, and such electro-optical systems as image converters and image intensifiers. Pertinent details of the instrument setup for these various applications as well as data on numerous devices will be presented. Instrument accuracies and error analysis will be discussed along with details of y-axis normalization.
