摘要： Method and apparatus for a multi-application, laser-array-based image system utilizes three linear laser arrays. Each linear array generates multiple (N>1) parallel output beamlets at one of the three primary colors (red, green, blue). The corresponding 1 to N output beamlets of the three linear arrays, each individually modulated in luminance according to a specific encoding scheme representing the video image to be produced on the viewing screen, are combined spatially to form a single white light linear array source. Through a projection/scanner optical system, the N output beamlets of the white light source are simultaneously directed to, and swept horizontally across a distant viewing screen, resulting in a swath of N lines of a graphic video image. By producing M contiguous swaths vertically down the viewing screen, a full image of M.times.N lines is produced. The red, green, and blue linear laser arrays may consist of arrays of semiconductor laser diodes made of suitable semiconductor materials so as to directly emit radiation at wavelengths corresponding to red, green, and blue colors, respectively. Alternatively, the red, green and blue color arrays may be formed by arrays of semiconductor laser diodes emitting radiation at twice the desired red, green and blue wavelengths, whose radiation is coupled to arrays of second harmonic generation crystal elements.

摘要： Filtering apparatus responsive to a sequence of samples of an input signal that is digitally-sampled at a given frequency, wherein the input signal defines information having at least one dimension. The apparatus includes first resampler for resampling the input-signal to derive a first signal at a first frequency which is substantially equal to the reciprocal 1/C of a given factor C times the given frequency, and second resampler for resampling the first signal to derive a second signal at a second frequency which is substantially equal to the given factor C times the first frequency. The given factor C is an improper fraction having a least-common-denominator larger than one. This filtering apparatus is particularly suitable for variably spatially low-pass, high-pass, band-pass or hierarchical-pyramid filtering two-dimensional image information in each of its two-dimensions by amounts which are independent of one another.

摘要： Pipe-line architecture is employed for analyzing in delayed real time the frequency spectrum of an information component (having one or more dimensions) of a given temporal signal having a highest frequency of interest of no greater than f.sub.0, and/or for synthesizing in delayed real time such a temporal signal from the analyzed frequency spectrum thereof. Such pipe-line architecture is particularly suitable for image-processing the two-dimensional spatial frequencies of television images defined by a temporal video signal.

摘要： A digital resampler comprises a combination of first means and second means. The first means, which includes interpolation filter means, is responsive to the digital-signal sample values of an input sample stream for producing a first derived sample stream of digital-signal sample values in which the given sampling period P of the input stream is multiplied directly by a factor equal to M'/CL, where C is a given positive integer and M' is smaller than CL, either 2.sup.n (M'/CL) or 2.sup.-n (M'/CL) is equal to M/L and the absolute value of n is at least equal to zero, so that the sampling period of the first derived sample stream is (M'/CL)P. The second means, which includes octave prefiltering and sample means, is responsive to the first derived sample stream of digital-signal sample values for producing as an output a second derived sample stream of digital-signal sample values in which the first derived sampling period (M'/CL)P of the first derived sample stream is multiplied by a factor equal to either 2.sup.n (M'/CL) or 2.sup.-n (M'/CL), so that the sampling period of the second derived sample stream is (M/L)P.
