RAPID SWITCHING SLIT SCAN IMAGE CAPTURE SYSTEM

摘要

A slit scan image capture system for obtaining slit images of a patient's eye. At least two slit masks or two moving mirrors are associated with at least two rapid switching light sources for illuminating slit images on a patient's eye. Two motors each are connected to the slit masks or movable mirrors for incrementally moving the illuminated slits across the eye to a plurality of positions. A video camera captures images of the illuminated slits on the eye and a frame grabber is connected to the video camera for storing the captured images. The rapid switching light sources are powered-up to an approximately full power state and powered-down to an effectively off state in an amount of time less than an amount of time required by the motors to move the slit masks or movable mirrors from one position to a next position. This minimizes the amount of time required to capture a plurality of slit images across major portions of the patient's eyes.
