    摘要: Methods and apparatuses are provided for reducing reflections in optical systems. Two optical elements are spaced apart from each other with first surfaces facing each other to form a gap there between. Reflections from a light beam passing through the two optical elements are at a non-zero angle with respect to the light beam. A second surface of one of the optical elements is essentially perpendicular to the light beam.

    摘要: A system and method for encryption of a holographic image is disclosed. The method includes the operation of producing a beam of light having at least two wavelengths of light. The beam of light can be split to form an illumination beam and a reference beam. Amplitude information can be added to the illumination beam with an intensity control device to form an object beam. Wavelength information can be selected in the object beam to form a spatial color modulated object beam. The reference beam and spatial color modulated object beam can be directed to a predetermined location on the holographic media to interfere to record an interference pattern.

    摘要: A projection system including an illumination source providing an illumination beam, a modulator configured to modulate the illumination beam based on an image signal to form an image beam, and a projection lens having an aberration profile and comprising a catadioptric lens. The image signal is adjusted based on the aberration profile of the projection lens. The catadioptric lens is configured to receive the image beam along a first optical axis and fold and direct the image beam along a second optical axis such that a fold angle between the first and second optical axes is within a desired range.

    摘要: A modulator for a projection system includes a surface having a number of pixels defined thereon corresponding to pixels of the projection system. The pixel areas have shapes that counter a distortion of a lens of the projection system, such that distortion effects of the lens are reduced, and/or the side profile of the surface matches a field curvature of the lens of the projection system, such that field curvature effects of the lens are reduced.
