Abstract:

This report consists of two major parts. The first part contains a description of the Seeing Monitor, a system that was designed, fabricated, and tested on this program. The Seeing Monitor is an optical instrument that samples star images on a millisecond time scale and provides information on atmospheric seeing conditions. In this system star images are scanned in orthogonal directions by a spinning reticle wheel and the light transmitted through the wheel is processed to yield the modulation transfer function of the atmosphere, the seeing angle, and image wander information. The Seeing Monitor test results show satisfactory performance for stars of visual magnitude up to about 6.5 and a dynamic range for seeing angles of 0.1 to 10 arc seconds. The second part of the report describes a series of experiments and computer simulations that were performed in preparation for a feasibility demonstration experiment of Polarization Reference Imaging PRIM at AMOS. The experiments performed in the laboratory at HRL as well as the ruby laser experiments at amos all indicate that the demonstration experiment is feasible.
