Abstract

The invention discloses an optical coherence chromatography system with an adjustable working wavelength and a wide bandwidth range; the optical coherence chromatography system comprises a laser, a sample arm, a reference arm, a spectrum receiving device, an optical coupler and a filter, wherein the filter comprises a D-shaped reflector, a prism pair, a shielding object and a first reflector; thelaser emits composite light; the composite light enters the filter to be filtered and then enters the sample arm and the reference arm; and the light reflected by the sample arm and the reference armforms interference fringes in the optical coupler to be transmitted to the spectrum receiving device to complete the coherent chromatography of the sample. According to the optical coherence chromatography system, the wavelength and the bandwidth are adjusted by the aid of the filter, so that the working wavelength and the bandwidth of the whole optical coherence chromatography system can be adjusted, and the optical coherence chromatography system is convenient to adapt to different detection environments. The optical coherence chromatography system is mainly used in the technical field of optical coherence tomography equipment.
