Problems solved by technology

Its disadvantages are: 1. Only a single optical fiber is used to illuminate the fiber bundle to play the role of lighting
2. This optical system does not have any requirements for aberrations, nor does it correct any aberrations, so it can only be used in general lighting systems, and cannot be used in any other optical systems that require higher imaging quality of the optical system

Abstract

Disclosed is an optical system which comprises: X axis scanning lens, Y axis scanning lens, telescope system, scanning coupling lens system, imaging fiber beam and refractivity matching liquid; wherein the telescope system is positioned at the back of the X axis scanning lens, front of Y axis scanning lens; scanning coupling lens system is positioned at the back of scanning lens; between scanning coupling lens system and imaging fiber beam being filled with refractivity matching liquid; the imaging fiber beam is positioned at the back of scanning coupling lens ; the magnification ratio of telescope system matches with the size of entrance pupil of scanning coupling lens system, effective surface of Y axis scanning lens and the size of emergent pupil of telescope system; the entrance pupil of scanning lens coupling system matches with the effective area of Y axis scanning lens.

Description

technical field [0001] The invention relates to the technical field of system optics, in particular to an optical system in which an imaging fiber bundle is coupled with a scanning optical system. Background technique [0002] At present, the confocal system is widely used in various fields of medicine due to its clear imaging, continuous slice scanning and image reconstruction, multi-label technology, live observation and quantitative information, etc., with high imaging contrast and resolution. big effect. However, when this system observes tissues, it must take out the internal organs of the human body, and then perform imaging and analysis, which not only increases the pain of the patient, but also prolongs the diagnosis cycle, so it cannot be popularized clinically. This limitation prompted the development of fiber optic confocal microscopy. Fiber optics create a flexible form of connection between the objective lens of the confocal microscope and the rest of the syst...
