Abstract
The invention provides AO-OCT imaging equipment which is convenient to distinguish diabetic retinopathy from MacTel disease. The equipment comprises a light source, a plurality of optical transmissioncomponents, an optical fiber coupler, a reference arm, a sample arm, a spectrometer and a camera, wherein the central wavelength of the light source is 840 nm. The imaging equipment adopts an adaptive optical coherence tomography technology to optimize the optical path design and component selection, especially uses a deformable reflecting mirror based on MEMS and a Shack-Hartmann wavefront sensor based on high-speed CMOS, and thus the cost, size and complexity of the traditional deformable mirror are greatly reduced; and the equipment enables the AO-OCT to penetrate deeply, can perform high-resolution imaging on a deep retinal vascular layer, and thus the changes of capillary microvessels caused by the two diseases can be distinguished, so that wider acceptance is obtained.
Description
technical field [0001] The invention belongs to the technical field of optical detection, and in particular relates to an AO-OCT imaging device which is convenient for distinguishing diabetes mellitus and MacTel disease. Background technique [0002] The full name of diabetic retinopathy is "diabetic retinopathy". Diabetic retinopathy is the most common special microvascular complication of diabetes. Its relative irreversibility and serious damage to vision have caused great harm to the lives of patients and blinded adults. the main reason. Early stage patients generally present with retinal microaneurysms, hard exudates, changes in retinal veins, and even new blood vessels. In the early stage, there are no ocular symptoms, and the effective period of the best treatment has been lost when the visual acuity is significantly reduced, and the late stage can lead to irreversible blindness. Therefore, it is particularly important to make an accurate diagnosis of diabetic retino...
