Abstract
This paper is an extension of previous work which dealt with characterizing the performance of staring PtSi infrared cameras, based on estimating their spatial frequency response. Applying a modified knife edge technique, we arrive at an estimate of the edge spread function (ESF), which is used to obtain a profile through the center of the two-dimensional modulation transfer function (MTF). In this paper, we demonstrate that this technique is applicable as a field measurement. The resolution of the system can be calculated using the width of the line spread function (LSF) and an image of an object of known width. In addition, by applying this technique at long range, the MTF of the atmosphere can be measured.
