Abstract
A method and system for rate sensitive blanking in a path length control circuit of a gyroscope is provided. The method comprises determining an angular rate of the gyroscope, detecting a zero rate of the gyroscope where one or more single beam signals occur, and determining one or more blanker positions based on the zero rate. A blanker pulse is generated at the blanker positions such that the path length control circuit suspends operation when the one or more single beam signals occur.
