Paper Abstract

As discussed in a previous paper to this forum, optical components such as collimators that are part of many infrared projection systems can lead to significant distortions in the sensed position of projected objects versus their true position. The previous paper discussed the removal of these distortions in a single waveband through a polynomial correction process. This correction was applied during post-processing of the data from the infrared camera-under-test. This paper extends the correction technique to two-color infrared projection. The extension of the technique allows the distortions in the individual bands to be corrected, as well as providing for alignment of the two color channels at the aperture of the camera-under-test. The co-alignment of the two color channels is obtained through the application of the distortion removal function to the object position data prior to object projection.
