摘要： A display system for acting on light entering the system includes a reflective ferroelectric liquid crystal spatial light modulator and a polarizer arrangement. The polarizer arrangement includes a polarizer for polarizing the light entering the system and directing the polarized light into the spatial light modulator along an optical path having an optical path axis. The reflective spatial light modulator acts on the polarized light to produce an optical output that is directed from the spatial light modulator back into the polarizing arrangement along substantially the same optical path axis that the polarized light is directed into the spatial light modulator. The polarizing arrangement also includes an analyzer configured to receive and analyze the optical output of the spatial light modulator and to direct the analyzed optical output out of the system. A compensator is positioned in the optical path between the polarizer of the polarizing arrangement and the spatial light modulator and in the optical path between the spatial light modulator and the analyzer. The compensator includes a layer of ferroelectric liquid crystal light modulating medium switchable between a first compensator state and a second compensator state. The compensator is configured such that the compensator inverts the optical output of the spatial light modulator when the compensator is switched to the second state. The layer of ferroelectric liquid crystal light modulating medium of the compensator and the spatial light modulator having retardances that are substantially different than one another.

摘要： An assembly for producing a visual display includes a light-reflecting type spatial light modulator and an illumination arrangement for providing a particular source of light. The spatial light modulator has a light reflecting surface cooperating with a light modulating medium switchable between different states so as to act on light in ways which form an overall pattern of reflected, modulated light. The spatial light modulator also has an arrangement for switching the modulating medium between the different states in a controlled way so as to form the overall pattern. The overall assembly further includes an optics arrangement having a first member defining a light reflecting surface. The optics arrangement also has a second member defining (i) a first external face located in proximity to the illumination arrangement, (ii) a second external face located in proximity to the spatial light modulator, (iii) a third external face located in proximity to the light reflecting surface of the first member, and (iv) a fourth external face. The optics arrangement cooperates with the illumination arrangement and the spatial light modulator such that the spatial light modulator forms the overall pattern of modulated light from light provided by the particular source of light and such that the light reflecting surface of the first member forms a magnified image of the overall pattern which is viewable from within a predetermined area which extends away from the fourth face of the second member.

摘要： A system and method for producing spatially modulated monochrome or color light having gray scale during a given period of time includes a spatial light modulator having a light modulating arrangement switchable between different states so as to act on light in different ways. A switching arrangement switches the modulating arrangement between different states in a controlled way during the period. The system also includes an illumination arrangement for selectively and alternately directing light of constant intensity and varying intensity into the modulating arrangement during predetermined subperiods of the period. In a color version of the system, the illumination arrangement directs light of different colors into the modulating arrangement during predetermined subperiods of the period, thereby providing a system for producing modulated colored light having color gray scale during a given period. In one embodiment of the present invention, the predetermined subperiods include a first plurality of subperiods of unequal lengths of time which, if arranged in order timewise, increase in duration by a factor of two. The predetermined subperiods further include a second plurality of subperiods and the illumination arrangement directs light of variable intensities into the modulator arrangement during each of the second plurality of subperiods which are of equal durations. Each of the different intensities of light double from subperiod to subperiod when the subperiods of equal length are arranged in a particular order.
