Embodiment Construction

[0063] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0064] refer to figure 1 and combine figure 2 , a fundus camera combined with an OCT system of the present invention includes an OCT module 50, a first beamsplitter 512, a second beamsplitter 307, a first aperture stop 203, an objective lens 201, an imaging optical path and an illumination optical path. Specifically, refer to figure 2 , the OCT module 50 includes: an OCT system light source 501, a fiber coupler 502, a reference arm module 50B, a detection system 506, a control system 507 and a sample arm module 50A. Wherein, the reference arm module 50B includ...

Abstract

The invention discloses a fundus camera combined with an OCT system. The fundus camera combined with the OCT system comprises an OCT module, a first spectroscope, a second spectroscope, a first trepanned diaphragm, an eye lens, an illumination light path and an imaging light path. The OCT model provides reference light and detecting light. The reference light returns after reflected through the fundus and generates interference with reference light returned from a reference arm module in an optical fiber coupler, interference light is detected by a detection system and processed through a control system, and an OCT image of the human eye is displayed. The illumination light path provides illumination light entering the fundus of the human eye, and the illumination light enters an imaging light path shooting human eye fundus images after being reflected by the fundus. According to the fundus camera combined with the OCT system, when tomography imaging is carried out on the fundus, the detecting light does not need to pass through a flexor adjusting lens of the imaging light path, the power of OCT signal light entering the human eye fundus cannot be influenced by flexor adjustment of the flexor adjusting lens, and therefore good OCT images of human eye fundi of different refractions can be obtained.

Description

technical field [0001] The invention relates to the field of optoelectronics, in particular to a fundus camera combined with an OCT system. Background technique [0002] The existing fundus cameras usually adjust the clarity of the infrared fundus preview image through the adjustment mirror of the imaging optical path, or judge whether to adjust the imaging optical path to the best state according to the auxiliary adjustment and alignment optical path, and then the ophthalmologist The OCT system performs flash photography to obtain fundus images. But the definition of the fundus image obtained by this method is not high enough. In addition, the patent application document with the application number 200710302263.8 discloses a technical means of connecting the OCT unit to the imaging optical path of the fundus camera. This method can improve the clarity of the fundus image. However, in this patent, there are also defects. With reference to the accompanying drawings of the ...
