Abstract The movable mirror is used to distinguish optical path difference in a continuous scanning FTIR. Moving mirror scanning system is the only moving part in FTS, the accuracy of scan and the distance of scan, would affect the signal to noise ratio (SNR), repeatability and resolution of the instrument directly. A moving mirror scanning system that based on flex cross-spring pivots were designed, and a fuzzy controller was designed to ensure that the movement of the moving mirror system is collimated, uniform and smooth,with the control accuracy up to 99.8%.
