  • Patent number: 6952435
    Abstract: The present invention contemplates a method and apparatus to generate a laser probe beam free of speckles. The present invention employs a holographic phase plate inserted in a laser beam path to modulate the relative phase across the beam. The holographic phase plate is designed to optimize the phase modulation across the beam while to minimize the degradation of the beam quality. The modulated laser beam has only a small and confined divergent angle and can then be refocused or collimated into a narrow and near collimated probe beam. The present invention further rotates the holographic phase plate to randomize the speckles in a time sequence. As a result, the probe beam preserves substantially the beam quality of a laser and produces substantially no speckles on image of its, intersection with a surface or material.

    Abstract: A disclosed exposure device performs controlling exposing dose by gradations of {n×(m−1)+1} stages representing shadow to highlight for each color when exposing the maximum n times under a condition that every light-emitting element is exposure-gradation controlled independently at m-stages. When a silver halide photosensitive material is used as a photosensitive material, light sensitivity is high in the order of red, green and blue. The number of aligned rows of red light-emitting elements is greater than those of aligned rows of other colors for reducing the light-emitting intensity on a time-average basis for every red light-emitting element. The area of red light-emitting elements and the area of green and blue light-emitting elements are simultaneously and independently passive-matrix driven by corresponding driving circuits. Of each light-emitting element, the driving duty improves and the peak light-emitting intensity reduces.
