Abstract

DIPOLE MASS LASER-BASED GRAVITY GRADIOMETER A gravity gradiometer using at least one mass dipole mounted in a laser force-measurement system to detect the torque on the mass dipole generated by gravity gradient. The mass dipole is mounted on one end of a photoelastic modulator element positioned in the laser beam to differentially modulate circular polarization modes in response to application of a torque. In a preferred form, two mass dipoles are mounted on opposite ends of the modulator element which is rigidly supported at its center to improve noise rejection.
