ABSTRACT:
The device and method of the present invention are useful for determining the characteristics of an infrared wavefront. The present invention involves positioning a beam of light containing the infrared wavefront to be characterized onto a distorted grating, using the grating to produce a plurality of images, determining the infrared wavefront from the plurality of images and analyzing the infrared wavefront for features that characterize the infrared wavefront.
