Abstract

The invention relates to a retina optical coherence chromatography detection-display system. The retina optical coherence chromatography detection-display system comprises a first light path channel for displaying image information, a second light path channel for tracking retina information, a third light path channel formed by an external natural light channel and a fourth light path channel for detecting pupils. In combination with the optical waveguide display technology and the Michelson interference technology, the retina optical coherence chromatography detection-display system overcomes the defects of an original retina optical coherence chromatography detection system, can detect the structure of the retina, can be used for studying the relations between pupil movement, dilation and miosis and structural features of the retina by changing displayed images, also has fluoroscopy and display functions and can be applied to medical research, pathologic analysis, lie detection and other aspects.

Description

technical field [0001] The invention relates to retinal optical coherence tomography technology, in particular to a retinal optical coherence tomography detection-display system. Background technique [0002] Retinal coherence tomography technology uses infrared weak coherent light to irradiate the retinal tissue to be tested, and generates interference according to the coherence of the light. After analyzing and processing the coherent signal, the retinal tissue surface image is formed. It has non-radiation, non-invasive, and high axial resolution. , The advantages of real-time imaging. Retinal optical coherence tomography is an optical instrument that uses this technology to analyze retinal structures and detect retinal lesions. The retinal optical coherence tomography detection system and the signal acquisition and processing system are important components of the retinal optical coherence tomography. Its basic principle is as figure 1 As shown, the infrared laser sour...
