Abstract: A pupil tracking system including a light source for illuminating a viewer's eye, an aperture located to pass light from the light source after retro-reflection from the viewer's pupil, the aperture sized and shaped to pass the light from the light source and block at least a portion of other light arriving at the aperture, and a light sensor for tracking a location of a spot produced by the light from the light source which passed the aperture. Related apparatus and methods are also described.

Abstract: A method for improving a display of an interference based computer generated holographic (CGH) image including reducing an effect of a Zero Order Diffraction (ZOD) bright spot on the CGH image by performing at least one action from a group consisting of apodizing the illuminating the SLM, redirecting light reflected from a face of the SLM to a different direction than light modulated by the SLM, apodizing light modulated by the SLM, shifting a location of the ZOD bright spot along an optical axis of the displaying the CGH image, shifting a location of the ZOD bright spot sideways relative to the optical axis of the displaying the CGH image, blocking light which produces the ZOD bright spot, and blocking light which produces the ZOD bright spot and also filling-in a dark spot produced by the blocking. Related apparatus and methods are also described.
