Abstract

This paper describes a method which can be used to measure the point spread function of thermal imager. The images of a sharp thermal edge at 36 different orientations are digitally processed to produce line spread functions which are projections of the point spread function. For the reconstruction of the point spread function, the filtered-backprojection algorithm is applied. The experi mental result has been presented with the discussion.
