Design of the AFGL Prototype Long Baseline Tiltmeter.

Abstract

This report describes the design of a prototype long baseline tiltmeter that has been built and tested. A discussion of the mechanical tank and interferometer system, sensor electronics and interface, and the computer system is included. Results of a two day test are described. The prototype tiltmeter shows a high dependence upon temperature variation. This must be eliminated if the tiltmeter is to be reliable over long periods of time. Keywords: Tiltmeter; Interferometer; and Photo diode array.
