ABSTRACT:
A contact free optical motion sensor for an inertial reference system. One or more image acquisition systems are adapted to produce a series of overlapping images of a gas bearing supported spherical inertial sensor assembly. A controller coupled to receive the series of overlapping images applies a delta detection algorithm to the series of overlapping images to determine the distance, the direction of movement of the inertial sensor assembly and the resulting relative position of the gas bearing supported spherical inertial sensor assembly. The controller further calculates the rotational velocity of the inertial sensor assembly based on a time sequence between the received series of image signals and the distance moved.
