A method and system are provided for sensing eye motion, such as saccadic eye motion, in a non-intrusive fashion. An optical delivery arrangement converts a laser beam pulse into a plurality of light spots. The light spots are focused such that they are incident on a corresponding plurality of positions located on a boundary whose movement is coincident with that of eye motion. The boundary can be defined by two visually adjoining surfaces having different coefficients of reflection. Energy is reflected from each of the positions located on the boundary receiving the light spots. An optical receiving arrangement detects the reflected energy from each of the positions. Changes in reflected energy at one or more of the positions is indicative of eye motion.

[ What is claimed as new and desired to be secured by Letters Patent of the United States is:] [1.]1. A system for sensing eye movement, the system comprising:a light source providing a pulsed light beam;an optical delivery arrangement operable with said light source for converting each pulse of said pulsed light beam into a plurality of light spots and for focusing said plurality of light spots to be incident on a corresponding plurality of positions located on a boundary whose movement is coincident with that of said eye movement, said boundary defined by two visually adjoining surfaces of the eye having different coefficients of reflection, wherein energy is reflected from each of said plurality of positions; andan optical receiving arrangement for detecting said reflected energy from each of said plurality of positions, wherein changes in said reflected energy at one or more of said positions is indicative of eye movement.
