    • A method for tracking lateral movement of an object is disclosed employing a retro-reflective disk as a positioning reference, and a simplified positioning detection to determine the position of the reference disk. The reference disk having a retro-reflective surface is affixed onto the object to be tracked. An illumination beam (4) illuminates the reference disk from one direction and imaging optics forms a bright image spot (5) of the reference disk with the backward scattering from the reference disk. A two-dimensional positioning detector (24) detects the position of the bright image spot and an electronic circuit (25) then generates positioning signals (26) of the object for tracking applications. The bright image spot of the reference disk enables the use of single element two-dimensional positioning detector, and thus enables fast detection (⊃ >1 kHz) of the object's position. An embodiment of the method on an eye-tracking system is described.
