An imaging system can include a segmented modulator, for example, a spatial light modulator, that is segmented into two or more equally or differently sized regions, and utilized to create a 3D, pseudo 3D, hologram, pseudo hologram, holographic, or pseudo holographic image. A voltage control unit is coupled to the spatial light modulator and controls voltages across each of the regions, wherein the voltage across one of the regions differs from the voltage across another one of the regions.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Application No. 62 / 473,307, entitled IMAGING SYSTEMS AND METHODS, and filed Mar. 17, 2017, the entire disclosure of which is incorporated by reference.FIELD OF THE INVENTION[0002]The present invention is directed to display systems and methods. More particularly, the present invention relates to systems and methods for forming one or more images utilizing a segmented display.BACKGROUND OF THE INVENTION[0003]Systems for displaying images may involve many components, for example light sources, displays, and optical devices. For wearable augmented and virtual reality systems, which generate images, the number of components is a significant factor in the design of such systems. In designing wearable systems, for example, the design objectives may include minimizing the size and weight of the devices or systems. In addition, when the number of components increases, the cost associated with d...
