title: Photosensor aperture shaping to reduce aliasing in optical-mechanical line-scan imaging systems.
abstract: Optical-mechanical scanning techniques are generally employed in instruments specifically designed to characterize variations in scene brightness spectrally or radiometrically. The effect of aliasing, which can be caused by line-scan sampling, on the spatial detail of the reconstructed image has therefore been of little concern. Emphasis of some recent applications of optical-mechanical scanning techniques is, however, on the spatial characterization of the scene. As is shown here, such images can be severely degraded by aliasing. Photosensor aperture shaping and line-scan spacing are investigated as a means for reducing this degradation.
