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

Abstract

During the first two months of this project. Physical Optics Corporation (POC) analytically evaluated the depth discrimination properties of a pixel filter. Numerical simulation results indicate that pixel filters have fine depth discrimination capability. Following the numerical analysis, we started to design experiments to verify the capability of the pixel filter. We performed two experiments: first, we measured the light intensity as a function of depth; second, we conducted measurements in the frequency domain as a function of depth. In the frequency domain, measurements are insensitive to fluctuations in light intensity; thus, a higher signal/noise ratio can be expected.
