Abstract
Disclosed herein is an External Scatter Removal System for Ring Laser Gyroscopes (such as a Split Gain Multioscillator) comprising a prism mounted on an optoisolator, wherein light transmitted out at least one of the mirrors of the Gyroscope passes into the prism and detector system, while oppositely directed backscattered light from the prism components is not returned to the gyroscope frame's internal optical path, thereby limiting any appreciable backscatter from interfering with an accurate measurement of the rotation rate of the gyroscope.
