Problems solved by technology

For this reason, if the retinal cell microscopic imaging system cannot image in layers, each layer of cells will be imaged on the imaging surface at the same time. It is quite difficult to clearly distinguish each layer of cells on this image. Imaging system can not be layered imaging will seriously restrict its role

Embodiment

[0015] Example: such as figure 1 As shown, a retinal cell microscopic imaging system capable of layered scanning includes an illumination system, a layered scanning optical unit, and a microscopic imaging optical unit.

[0016] from lighting systems such as figure 1 As shown, the parallel incident light beam composed of mirror 101 to bandpass filter 113) is reflected by the first polarizing beam splitting prism PBS401, enters the layered scanning optical unit, and then is focused by the dioptric body of the human eye.

[0017] The layered scanning optical unit includes a first objective lens 501 and a second objective lens 502 . Wherein, the first objective lens 501 and / or the second objective lens 502 can move with a precise distance. In this embodiment, the first objective lens 501 is chosen to be fixed, and the second objective lens 502 can move precisely along the axial direction.

[0018] The layered scanning optical unit can not only adjust the diopter of the human ey...

Abstract

The present invention discloses a retina cell microscopic imaging system which can conduct stratified scanning and comprises an illuminating system and a microscopic imaging optical unit. The inside of an optical path between the illuminating system and a human eye (601) is provided with a stratified scanning optical unit which comprises a first object lens (501) and a second object lens (502). The first object lens (501) and / or the second object lens (502) can move critically along the axial direction. The parallel incident illumination beams of the illuminating system are focused on certainfilm inside a human eye retina (603) through the second object lens (502) and the first object lens (501) sequentially. During the stratified scanning, a focusing face formed on the retina (603) moves correspondingly at each cell layer inside the retina (603) along with the movement of the first object lens (501) and the second object lens (502). A small depth of focus imaging optical unit is used as the microscopic imaging optical unit. The retina cell microscopic imaging system of the present invention has simple structure and can effectively conduct stratified observation towards each filmforming the retina.

Description

technical field [0001] The invention relates to a retinal cell microscopic imaging system, in particular to a retinal cell microscopic imaging system capable of layered scanning. Background technique [0002] In the existing microscopic imaging system of retinal cells, no layered scanning of the retina is involved. For example: the retinal cell microscopic imaging system described in patents CN99115051.1, CN99115052.X, CN99115053.8 and CN99115054.6 of the Institute of Optoelectronic Technology, Chinese Academy of Sciences. [0003] Since the retina is a phase-type, transparent tissue structure with a total thickness of only a few hundred microns, there are multi-layer structures distributed within this thickness range, and each layer is distributed with different cell tissues. The distribution of various cells and their Changes are closely related to diseases and their changes, so it is desirable to have a layered view of the layers that make up the retina. In fact, if the...
