Abstract:

In this project, POC advanced and optimized a spatial filtering technique for measuring irradiance spatial density. The key component of the novel technique is a pixel filter placed at the image focal plane. The pixel filter design includes a wavefront-matched filter, a microlens, and a point detector. The pixel filter allows the light from the in-focus volume to pass, suppressing the light from out-of-focus areas. Three objectives were established for the Phase I project and its Option Task. This report does not concern the Option Task since that task has not been performed yet. The objectives were Objective 1 Numerically analyze and characterize the properties of an imaging system using the proposed 3-D spatial filtering technique, and determine optimal system design parameters Objective 2 Construct a single pixel filter, and experimentally demonstrate the proof-of-concept of the technique and Objective 3 Identify work to be performed in Phase II of this research.
