Geophone element testing

Malcolm B. Bertram and Eric V. Gallant

ABSTRACT

A new system incorporating a laser interferometer for measuring geophoneelement characteristics is being developed. The purpose is to determine absolute measurements of linearity, distortion and phase for elements of different frequency, manufacture and orientation. This apparatus will also be used to measure the coupling of the elements in the auto-orienting sensor now in the process of being patented.
