Paper Abstract

Infrared projection systems commonly use a collimating optical system to make images of a projection device appear far away from the infrared camera observing the projector. These `collimators' produce distortions in the image seen by the camera. For many applications the distortions are negligible, and the major problem is simply shifting, rotating, and adjusting the magnification, so that the projector image is aligned with the camera. In a recent test performed in the Kinetic Kill Vehicle Hardware-in-the-Loop Simulator facility, it was necessary to correct for distortions as small as 1/10th the size of the camera pixels across the field of view of the camera. This paper describes measurements and analyses performed to determine the optical distortions, and methods used to correct them.
