Coherent Rear Projection Viewer Evaluation.

Abstract

The objective of this study was to evaluate the extent to which coherent array illumination, with respect to incoherent illumination, could improve the modulation of imaged high resolution, 15-bar, test targets. Targets tested ranged from a density difference of 0.3 to 1.0 in steps of 0.1. Points of focus for each target were 63.13, 100, 125.9, 158.5, and 199.6 LP/MM. The coherent array illumination yielded significant increases in modulation at 100 LP/MM and above. (Author)
