Abstract
A wide angle light intensity pickoff system, having a very fine signal reution of less than a degree, provides a linear range of about .+-.35 degrees with a total range of .+-.90 degrees. The pickoff system can be used with any angular measurement system. In a gyro system all of the active circuit components, an offset optical source and a detector, are mounted on the unstabilized housing structure. Only a fiber optic bundle is required on the stabilized gimbal for coupling optical signals to the detector. There is no mechanical contact between the stabilized gimbal and the unstabilized housing structure. This prevents gimbal/housing coupling torques while providing a wide angle pickoff capability.
