PERFORMANCE REQUIREMENTS FOR A HIGH-FREQUENCY TWO-AXIS ANGULAR VIBRATOR. (2005)
Sher, Lawrence, Weinstock, Herbert
The need for a two-axis angular vibrator for the testing of gyroscopic instruments whose frequency range extends beyond the 100-cps capability of present machines is demonstrated. An outline of the...
Cross Coupling Effects in a Telescope System. (1998)
Sher,Lawrence, Johnson,Robert J., DeHainaut,Christopher
Cross coupling effects in a precision telescope system have been investigated. Two mechanisms for the cross coupling were examined, gyroscope output axis coupling and anisoinertia anisoinertia...
Angular Vibration Effects on a Telescope System. (1998)
The optical system considered here consists of a pointing system used to direct a laser beam from an aircraft. The laser is located on the floor of the aircraft, and its beam is relayed by a mirror...
