Design of the AFGL Prototype Long Baseline Tiltmeter I. INTRODUCTION ' The spatial distribution and magnitude of crustal tilt remains largely unknown. Information on crustal tilt comes primarily from repeated historic geodetic meas- urements and tide gauge observations.

The AFGL Melting Layer study was begun in Original plans called for a flight program and extensive radar studies. Budget problems and a change in the AFGL meteorology program led to curtailment of these portions of the program. This report will therefore concentrate on those portions of the program that were.

A prototype instrument has been constructed using welded borosilicate with a pendulum length of m resulting in a main resonance frequency of Hz. Optical borehole tiltmeter design. This work describes the design, realization, and testing of a novel compact tiltmeter model, which is based on a simple free pendulum and optical detection.

Two equal prototypes were built and. We discuss the design principles involved in long baseline fluid tiltmeters and describe the construction and operation of a m long half-filled tube tiltmeter using laser-interferometer end. This allows simpler construction and instal- lation, the major requirement being to eliminate so far as possible any drift of the baseline with time.

The FP used as a tiltmeter has been studied in theory and demonstrated in prototype form. The sensitivity of the FP to the tilt tides is stable due to its symmetric structure and flat linkage foils.

Preliminary experimental result shows that the resolving power of the FP to the tilt tides has reached in the order of about ×10 −9 rad.Revised AFGL infrared sky survey catalog.
