Eliminating ring laser gyro backscatter

摘要

A ring laser gyroscope (RLG) block is provided. The RLG block includes a first corner bordered by a first portion of a first side and a first portion of a third side; a second corner bordered by a first portion of a second side and a second portion of the third side; and a third corner bordered by a second portion of the second side and a second portion of the first side. The first portion of the first side shifts the first corner laterally in a lasing plane of the RLG block, toward the second corner, and perpendicular to a first normal of a first mirror when a temperature change contracts the RLG block; and shifts the first corner laterally away from the second corner, and perpendicular to the first normal when the temperature change causes an expansion of the ring laser gyroscope block.
