Abstract: Image capture devices can include an image sensor, a color filter array, and an image processor. The image sensor can include an array of sensor elements configured to detect incoming light provided incident to a surface of the image sensor. The color filter array can be positioned adjacent to the image sensor for filtering the incoming light provided incident to the surface of the image sensor. The color filter array can include an array of filter elements including a plurality of clear filter elements and a plurality of color-sensitive filter elements. The plurality of color-sensitive filter elements can include at least one first color-sensitive filter element sensitive to a first band of the visible color spectrum and at least one second color-sensitive filter element sensitive to a second band of the visible color spectrum different than the first band.

Abstract: An optical interface of a holographic memory system electrically selects one of several optical pathways to store or retrieve an image from a holographic memory by activating liquid crystal polarization rotators and novel liquid crystal gratings. In a preferred embodiment a spatial light modulator, a pixelized readout device (i.e., focal-plane array), a series of polarizing optical components, liquid-crystal polarization rotators, liquid-crystal beam-steering devices, and interconnecting and imaging optics are provided. The parallel interconnection accepts a laser-beam input, divides the beam among multiple paths, imparts a data-bearing spatial signature on a signal beam by means of a spatial light modulator, steers a reference beam by means of liquid-crystal beam-steering devices, and directs the appropriate beams into the recording medium.
