Abstract

The invention provides an imaging device for cone cells. The imaging device comprises an AOSLO (Adaptive Optical Scanning Laser Ophthalmoscope), an OCT (Optical Coherence Tomography) and an imaging processing device. A light beam entering into cone cells of fundus is processed and returned through OCT and then is subjected to interference treatment with the light beam processed by AOSLO, and a processed interference signal is sent to the imaging processing device for generating a high-precision three-dimensional image, so that the activity of the cone cells of fundus can be observed.

Description

technical field [0001] The present invention generally relates to an imaging device, in particular to a cone cell imaging device. Background technique [0002] The application of adaptive optics (AO) in ophthalmology is to adaptively correct various aberrations of the optical system through the wavefront sensor-wavefront controller, and greatly improve the lateral resolution of the system. The human eye itself is an optical system, and the optical system often has various aberrations in the process of measuring the human eye, which seriously affects the image quality. Introducing adaptive optics technology into the optical system can solve this problem. This patent combines Adaptive Optics Scanning Laser Ophthalmoscope (AOSLO) with Optical Coherence Tomography (OCT) to greatly improve the resolution of the system in two-dimensional space and observe the cone-level activities caused by the system. The activity of the retinal layers can assess the activity of cone cells. ...
