Abstract

The invention discloses an optical coherence chromatography device with a compatible spectral information analysis function. The optical coherence chromatography device comprises a system light source (1), 1 / 99 light beam splitter (2), an auxiliary interferometer (15), a primary interferometer (16) and a collecting device (13). Interference signals generated by the auxiliary interferometer (15) are used as an external clock of the collecting device (13). The collecting device (13) is used for collecting electric signals outputted by a second balancing photoelectric detector (12) of the primary interferometer (16) according to the external clock, converging the electric signals to digital signals and inputting the digital signals into a computer (4). The computer (4) is used for carrying out data processing on the signals collected by the collecting device (13), and the data processing includes coherence chromatography imaging processing and spectral analysis processing. According to the device, the optical coherence chromatography imaging technology is used for locating pathological change positions or abnormal positions of biological tissues, and scattering information and spectral analysis information are combined so that more spectral analysis information can be easily obtained, and doctors or scientists can find more solutions. Through the optical coherence chromatography device, traumas caused by biopsy are avoided, and quick examination of lesions is achieved.

Description

technical field [0001] The invention belongs to the technical field of photoelectric detection combined with biological imaging, and in particular relates to an optical coherence tomography device compatible with spectral information analysis functions. Background technique [0002] Tomography refers to the cross-sectional imaging of the measured object, which is actually an inverse scattering problem: using the forward transmission data or backscattering data received by the object under the illumination of multi-angle or multi-frequency wave fields, Through the inversion algorithm, the relative position, geometric shape or intrinsic parameters of the scatterers in the object are obtained. Optical coherence imaging is the optical application of tomography. [0003] Optical coherence tomography combines advanced optical technology and ultra-sensitive detection, coupled with modern computer image processing, and has developed into a new tomographic diagnostic technology.
