Abstract: Smoking food items in a cold environment is carried out by utilizing an atmospherically sealed housing, in which at least one food item is placed, and subjecting the atmospherically sealed housing to a vacuum. Subsequently, the vacuum is partially released to draw in smoke from at least one other container that is connected to the atmospherically sealed housing. As the smoke is being drawn in from the other container it is being infused into the food item. The food item(s) is then rotated in the partial vacuum for a specific, but variable, amount of time, depending on the food item and the degree of flavor desired. The cycle may be repeated until the desired flavor is achieved. Once the desired flavor is achieved, the vacuum is completely released and the food item is removed and either cooked or stored for consumption at a later time.

Abstract: A system and method is presented for obtaining optical phase and amplitude measurements utilizing an acousto-optical modulator for modulating a laser light beam with a multifrequency electrical signal to form an image that is Fourier transformed and spatially distributed proportional to the frequency components of the electrical signal. An optical component such as a spatial light modulator is located in the Fourier plane and the modulated image is inversely transformed and optically heterodyned to produce a transformed image. The transformed image impinges a photodetector that produces an electrical output signal that is inputted to a network analyzer to measure phase and amplitude of the transformed image. The electrical output signal is compared with a reference signal and deviations from the reference signal provide a quantitative measurement of the phase and amplitude response of the spatial light modulator.

Abstract: Method of fabricating a coherently exposed multiple holographic lens including a first step of fabricating an incoherently exposed master multiple holographic lens with an array of overlapping holographic lens elements, each of said lens elements having an interference pattern substantially covering the entire area of the lens. The master multiple holographic lens is illuminated with a first beam of light from a coherent source to provide a plurality of light waves equal in number to the number of lens elements in the master lens. The plurality of light waves overlap in a region downstream of the master lens. A holographic recording medium is positioned in the region of overlap such that an area thereon is illuminated simultaneously by each of the plurality of light waves. A second beam of light from a coherent source is directed toward the area of the holographic recording medium illuminated by the plurality of light waves.
