Two motorsandorandeach are connected to the slit masksandor movable mirrorsandfor incrementally moving the illuminated slits across the eyeto plurality of positions. A video cameracaptures images of the illuminated slits on the eyeand a frame grabberis connected to the video camera for storing the captured images. The rapid switching light sourcesandare 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 motorsandorandto move the slit masksoror movable mirrorsandfrom 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
