Abstract

The invention discloses an eye-facing quick blood flow imaging optical coherence tomography (OCT) ophthalmoscope, which comprises a collimation light source, a beam splitting module, an interference system, a scanning device, a detector, and a collecting processor. The provided ophthalmoscope has been improved, on the basis of a conventional SLO ophthalmoscope, an interference system is added, a quick resonance type galvanometer and a slow galvanometer are combined to carry out scanning, vertical scanning is not needed to realize blood flow imaging, the pathological change of retina in a largefield range can be observed, and the comprehensive inspection and retina evaluation are promoted. Furthermore, the ophthalmoscope has the advantages of small volume, easy operation, and real-time image collection, and is easy to industrialize and popularize.

Description

technical field [0001] The invention relates to the technical field of fundus imaging inspection equipment, in particular to a coherent light scanning ophthalmoscope for rapid imaging of eye blood flow. Background technique [0002] Fundus imaging examination technology is an important method to check ophthalmic diseases. At present, fundus imaging examination equipment with relatively mature technology and relatively wide application includes Scanning Laser Ophthalmoscope (SLO for short) and Optical Coherence Tomography (OCT for short) system. [0003] The OCT system has the advantages of non-invasive, high-resolution, and quantitative evaluation in vivo. Its working principle is to use the principle of low-coherence interference combined with confocal scanning to perform high-resolution tomographic scanning of the microstructure inside biological tissues or other scattering media. , to reconstruct the image of the tested sample by computer. The core components of time-do...
