Apparatus for increasing the resolution of a laser gyroscope
This patent describes a laser gyroscope output signal generator for increasing a laser gyroscope output resolution. The signal generator is responsive to a sequence of pairs of phase shifted first and second laser gyroscope output pulses each being characterized to have a first and second logic state. The first and second output pulses in each pair have a leading or lagging phase relationship determined by the direction of rotation the laser gyroscope sourcing the pairs of phase shifted output pulses. The laser gyroscope output signal generator comprises: a first exclusive OR gate having inputs coupled to respective first and second laser gyroscope output pulses; and a first one-shot multivibrator having at least one input responsive to any state change at the output of the first exclusive OR gate to produce an output signal having a pulse recurrent frequency of four times that of the first laser gyroscope output pulse.
