Abstract
A contact free optical position sensor for an inertial reference system. The surface of an inertial sensor assembly is adapted with a coordinate encoded pattern. One or more optical sensors are adapted to generate image signals of the coordinate encoded pattern of the spherical inertial sensor assembly. A controller is coupled to receive the image signals from the optical sensors and adapted to apply a decoding algorithm to each image signal. The decoding algorithm determines the coordinates of the inertial sensor assembly images captured by each optical sensor and calculates the angular position of the inertial sensor assembly.
