摘要： A diffraction grating including a substrate, and a grating member formed on the substrate, the grating member having a stepped structure including steps, the number of which corresponds to an odd number greater than or equal to three to provide an odd phase structure. The heights of the steps of the grating member are determined such that the light beams diffracted by their corresponding steps substantially have a phase difference of π with reference to a diffracted light beam of a reference wavelength.

摘要： A laser television including a plurality of lasers for generating different wavelengths of interferential light; a scanner for displaying color images on a screen composed from the light; and a phase diffuser positioned between the lasers and the scanner for diffusing the light from the lasers according to the light's wavelength. The phase diffuser having a boundary surface, through which the light is outputted to the scanner. The boundary surface is slanted with a predetermined angle to regulate the range of diffraction of the light according to the wavelength.

摘要： Provided is an apparatus and method for preventing the distortion of an image. The apparatus includes a signal insertion portion that inserts a sensing signal in an image signal that has information about an image and outputs the image signal in which the sensing signal is inserted as a scanning signal. A scanning portion generates light corresponding to the scanning signal and scans the light while operating in response to a drive signal that determines a direction for scanning the light. A detection portion senses the scanned light and detects the sensing signal. A sensing condition reflection portion checks whether the detected sensing signal matches a preset sensing condition and resets at least one of the image signal and the drive signal in response to a result of the check.

摘要： The system includes an illumination system, a scanner, a non-linear optical element, and a pumping light source. The illumination system emits imaging beam and the scanner scans the beam incident from the illumination system. The non-linear optical element is made of a material having a Kerr effect or the like and forms a lens automatically aligned while following a path of the imaging beam scanned from the scanner. The pumping light source actives the non-linear optical element to cause a non-linear refractive index change of the non-linear optical element.
