Comparison of Noise Levels for Water Vapor Radiometers and the Troposphere
The Jet Propulsion Lab (JPL) has been appointed as NASA's division for unmanned space flight. Research in Very Long Baseline Interferometry (VLBI) is one aspect important to JPL. One of the largest error sources for ...
Comparison of Wet Troposphere Calibration Techniques and Their Effects on VLB I Geodetic Measurements
The water vapor in the troposphere is currently the largest source of error in VLBI geodetic measurements. Scientists have been working on this problem for over 10 years. Major improvements have been made. This report ...
An Interactive Program for Automating Optical Ray Tracing
The goal of my Senior Individualized Project was to design and code a Pascal program which helps Optics students develop an intuition for ray tracing. Users can graphically manipulate an object-lens system and observe ...
The Measurement of Birefringence and Dichroism of Substrate Samples
Current research in digital data storage is centered on developing a disk which can store data optically. However, in the process of reading back a signal from an optic disk, a degradation of the signal has been noticed. ...
A Student Experiment in Fourier Transform Spectroscopy
This project was to design and build an optical system for a student laboratory exercise that would allow the light from various discharge tubes to be analyzed. To test its operation, Sodium and Mercury sources were used. ...
The NRL Coronagraph: Resolution Testing of a Second Generation
During the Fall of 1985, I participated in the preliminary resolution testing of the prototype coronagraph. We experimentally determined many of its critical parameters, such as its angular field of view. Our main objective ...
