Eye imaging system

摘要

An eye imaging system, including: a light source module; a radial splitting module; a common optical module; an image receiver; a power supply module for the light source module; a driver module for the image receiver; a processing-displaying module; and a motion driving module. The image receiver is an area array sensor. The motion driving module is connected to the light source module and drives the light source module to move in a radial direction of an upstream illuminating optical path formed by the light source module and the radial splitting module. The image receiver continually opens for exposure in a radial direction of a downstream observation optical path formed by the radial splitting module and the image receiver. The continual opening of the image receiver for signal acquisition is synchronous with the movement of the light source module.

1. An eye imaging system for imaging an eye of a user, the eye having a width, the eye imaging system comprising:
a) a light source module; b) a splitting module; c) a common optical module; d) an image receiver; e) a power supply module; f) a driver module; g) a processing-displaying module; and h) a motion driving module;wherein:
the image receiver is an area array sensor; the light source module is adapted to generate a first light beam having a width substantially smaller than the width of the eye; the common optical module and the splitting module form a first optical path; the splitting module splits the first light beam into a second light beam and a third light beam; the second light beam transmits along the first optical path, reaches the eye, and illuminates part of the eye; the third light beam transmits along a second optical path perpendicular to the first optical path; the light source module is disposed on the first optical path and the image receiver is disposed on the second optical path, or the light source module is disposed on the second optical path and the image receiver is disposed on the first optical path; the motion driving module is connected to the light source module and drives the light source module to move, wherein when the light source module moves, the second light beam moves in a direction perpendicular to an optical axis of the eye; the image receiver opens and closes continually when the light source module moves, wherein when the image receiver opens, the image receiver receives a plurality of partial images of the eye; and the processing-displaying module combines the plurality of partial images of the eye and forms an overall image of the eye.
