Abstract

An auto-stereoscopic display system comprises image generating means for the generation of a pair of orthogonally polarised images to be transmitted along respective optical paths towards one or more observers for the illumination of at least a left hand part and a right hand part including the left eye and the right eye, respectively, and an optically addressed spatial light modulator (OASLM) including a plurality of light transmission elements, each being individually optically addressable, and each having an optical input and an optical output and being shiftable between a V-state and an H-state, in which V-state the transmission of vertically polarised light is allowed, and in which H-state the transmission of horizontally polarised light is allowed. Each of the light transmission elements has an optical sensor for the shifting between the V- and H-states through exposure to infrared radiation (IR). The OASLM is positioned in the optical paths form the image generating means to the one or more observers. The system further comprises an illumination system for illuminating the one or more observers for illumination of at least the left hand part or the right hand part of the head of each of the observers and in doing so, exposing a first part of the optical sensors of the OASLM to infrared radiation reflected from the left hand part or the right hand part of the head of each of the observers, the optical sensors of the first part shifting their respective light transmission elements into allowing transmission of a first image of the pair of orthogonally polarised images and the optical sensors not belonging to the first part shifting their respective light transmission elements into allowing transmission of the other or second image of the pair of orthogonally polarised images and a refractive optical system, including at least one retractive optical element positioned in front of the OASLM between the OASLM and the one or more observers for establishing the optical paths.
