A Novel Technique for 4-Dimensional Atmosphere and Oceanographic Irradiance Measurements Using 3-D Spatial Filtering.

Abstract

In the first two months of the program, Physical Optics Corporation has analytically evaluated the depth discrimination performance of pixel filters. These studies indicate that pixel filters have good depth discrimination capability for an array of discrete point light sources. The discrimination contrast is about 20:1. We also evaluated the effects of imaging lens aberrations and wavelength variation. This report describes in detail the numerical evaluation.
