Adaptive optical retina imaging device and method

Abstract

The present disclosure provides an adaptive optical retina imaging apparatus and method. The adaptive optical retina imaging apparatus comprises an optical processing unit, an adaptive optical unit, a two-dimensional scanning unit and a primary aberration correcting unit, in which an imaging unit included in the optical processing unit is imaging based on the signal after high order aberration compensation and low order aberration compensation. By combining the adaptive optical technique, a con-focal scanning technique and the optical coherence tomography technique, two wave front sensors are utilized to detect wave front aberrations between the con-focal scanning optical path and the optical coherence tomography optical path and two wave front correctors are utilized to correct low order aberration and high order aberration of human's eyes, so as to implement low order aberration and high order aberration for the two optical paths and to implement imaging of human's eyes in a higher transverse resolution and a higher longitudinal resolution.
