Endoscopic OCT (Optical Coherence Tomography) miniature probe, OCT imaging system and use method

The invention relates to the technical field of medical apparatus and instruments, and provides an OCT (Optical Coherence Tomography) miniature probe, an imaging system and a use method applied to endoscopic high-resolution OCT imaging. The OCT miniature probe is characterized in that the working distance of the OCT miniature probe can be changed through a lens assembly, and the clear aperture of a self-focusing lens is enlarged so as to improve the numerical aperture and the lateral resolution of the OCT miniature probe. According to the OCT miniature probe, the problems of low lateral resolution of the OCT miniature probe in the traditional OCT system and big possibility of deforming of a scanned image can be solved. Therefore, OCT endoscopic scanning imaging with the OCT miniature probe can be applied to human body tissue narrow space, such as blood vessels, digestive tracts and respiratory tracts.
