摘要: A system for determining a level of angle random walk (ARW) associated with fiber optic gyroscope (FOG) includes first and second photodiodes (115,135). The photodiode (115) is configured to receive light signal from source (105) the FOG. (135) coil First analog-to-digital converters (ADCs) (140) are operable respectively convert signals into corresponding respective digital signals. relative-intensity-noise (RIN) subtraction element (150) output third based on An electronic device determine noise signal, ARW level.
