摘要： An arrangement for sensing the wavelength shift of light from a polychromatic light source features a tilted concave holographic reflection grating that diffracts light from the light source and disperses the light across the focal plane of the arrangement. A pair of matched detectors disposed behind the focal plane senses the light transmitted by a variable neutral density filter at the focal plane. The difference in output signal electrical currents generated by the detectors is a measurement of the shift in polychromatic wavelength distribution.

摘要： An optical component consists of two or more plane-parallel windows with, respectively, two or more partially reflective surfaces. Each partially reflective surface splits off part of an original beam and produces another redirected beam. The redirected beam undergoes further redirection and attenuation by multiple reflections. Each even-numbered reflection produces a beam deviated from the original's beam direction by an even multiple of the angle between the windows. Thus, for a pair of windows a series of beams are produced that are in a straight line and are equally spaced.

摘要： A radiation image that has been stored in an image plate (19), such as a photostimulable phosphor screen is read by stimulating an information-bearing target area (13) with stimulating light (1). The information bearing target area responds to this stimulation by emitting information-bearing light (2) and reflecting backscatter light (3). The combination (4) of information-bearing light and backscatter light is collimated, allowing efficient rejection of backscatter light. The information-bearing light is subsequently focused onto an information receiving target (17), such as a charge-coupled device (CCD).

摘要： A collimated or partially collimated light beam is sent through a substrate matrix of a plurality of nested individual joined geometrically shaped cells wherein each of the cells contains a patterned holographic diffuser or binary optic sheet which produces a transmitted diffused light beam from each of the cells and then superimposes each transmitted diffused light beams from each of the cells to produce a combined resultant diffused light beam. The geometrically shaped cells are clustered in a contiguous arrangement of nested cell subgroups, which are themselves geometrically shaped. When graphed, an angular luminance distribution profile curve with sharply vertical profile slopes at halfpeak points and with a substantially flat and wide peak is resultant which produces a uniform resultant luminance over a wide range of view with a predetermined beam spread and beam deflection angle in relation to a predetermined location of view of the combined resultant diffused light beam.
