Optical coherent confocal microscopy endoscope system and realizing method

Abstract

The invention discloses an optical coherent confocal microscopy endoscope system and a realizing method. A section of 4F optical system is added to an OCT scanning imaging end; the section of optical system is conveniently used in an endoscope chamber, so that the pore diameter of an optical fiber of a sample arm is less than a minimal beam diameter (namely, minimum resolution of objective lens) on an imaging surface and the system has a confocal imaging effect; thus, the OCT resolution ratio can be obviously promoted while the imaging depth is not obviously reduced; the imaging effect similar to the confocal imaging effect can be achieved under the inexistence of dyeing; an MEMS micro-vibration mirror is combined for use, a GPU / FPGA algorithm is adopted and the present endoscope system is integrally used, so that the optical coherent confocal microscopy endoscope system can become a medical diagnosis tool with high speed, no dyeing, high sensitivity and specificity.

Description

Technical field [0001] The invention relates to a microendoscope system, in particular to an optical coherent confocal microendoscope system and an implementation method. Background technique [0002] In the field of medical diagnosis, because the lesions often occur on the superficial tissues, medical staff not only need to observe the microscopic imaging of the surface of biological tissues, but also hope to see the internal structure and morphology of the tissues, and find small lesions from it. For the existing tomographic imaging technology, such as ultrasound imaging, while having a deeper imaging depth, the resolution is low, which does not meet the needs of finding small lesions. [0003] Optical coherence tomography (OCT) as a high-resolution imaging method, its principle is based on low-coherence interference technology, combined with the advantages of heterodyne detection and conjugate imaging, to collect the reflected light signal collected from the sample end Calculat...
