Abstract:
     This invention relates to a fourier spectrometer based on dynamic stable scanning technology<0}. Wherein, it comprises a white light and laser source, an optical system mainly with Michelson interferometer, a feedback module to detect and convert the weak optical signal into electric signal, an A/D control module, an actuator module to control the phase difference of two arms of the interferometer, and a measurement module to detect the feedback and actuator modules for locked phase condition. This invention overcomes the defects in prior art, and can large-stroke continual scan with high precision, resolution and SNR.
