Abstract: A method for testing inertial measurement devices on a multi-axis rate table without having to utilize slip rings to transfer signals between the inertial measurement devices and remote processors by incorporating a processor internal to the inertial measurement devices and transferring the signals directly to the processors for determining and storing the calibration coefficients of the inertial measurement devices internally so that they are self calibrating.

Abstract: A dither motor for dithering a plurality of inertial sensors includes an outer support ring, a plurality of reeds and a plurality of mounting supports. The outer support ring may be generally circular or polygonal in shape. Each reed of the plurality of reeds has a hub end and an outer end wherein the hub ends are connected to a common hub and the ring ends are connected to the outer support ring. The plurality of reeds are arranged to be disposed at equal angles from each other and extend radially outwardly from the hub. The plurality of mounting supports extend outwardly from the hub and each mounting support is located between two of the plurality of reeds. The mounting supports are also equally spaced apart. Further, each reed has a means for oscillating connected thereto such as piezoelectric elements.

Abstract: A pair of flexure plates having an outer toroidal rim extended from a hub by a plurality of radial springs are utilized to rigidly sandwich a laser block. A housing having an aperture for receiving the sandwiched assembly is welded to the outer toroidal rims to provide a dither suspension mechanism for a ring laser angular rate sensor.

Abstract: An apparatus for determining fringe pattern movement particularly in the art of interferrometric devices. The apparatus of the present invention obtains precise movement of pattern movement without the use of any bias elements for maintaining sensitivity above zero.

Abstract: A dual polarization interferometer is employed for use as an angular rate sensor. A single waveguide is provided for propagating wave components of each of two polarized waves traveling in opposite directions. Each wave traveling through the waveguide is phase shifted by a value related to the rotation rate of the waveguide.
