    摘要： A system and method for reducing or eliminating speckle when using a coherent light source is provided. A refracting device is positioned such that a major surface of the refracting device is oblique to the axis of the coherent light and such that the coherent light passes through the refracting device. Because the refracting device is oblique to the incoming coherent light, the outgoing coherent light is offset from the axis of the incoming light. The refracting device may be rotated about an axis parallel to the incoming coherent light, thereby causing the outgoing coherent light to be rotated in an approximately circular orbit centered about the axis of the incoming coherent light.

    摘要： A cleaner for magnetic heads of tape recorders includes two gears centrally engaged with the revolving shaft of the recorder during use and pivotally installed in two revolving shaft holes on the tape cartridge respectively and peripherally engaged with each other. A plurality of projecting posts are spaced equally along the circumference in the planes of the two gears and alternately disposed in respect of each other post. A rocker is centrally and pivotally installed nearby the front end of tape recorder and between the two gears. Two opposite contact legs are provided to the rear end of the rocker and projected toward these posts respectively so as to contact these post alternately and respectively, and a cleaning element is installed on the front of the rocker. When this cleaner is installed in the tape recorder for use, the two gears rotate synchronously in opposite directions, the posts push and swing the rocker left and right alternately and respectively in sequence, so the rocker swings left and right and the cleaning element of the front end of rocker can clean the magnetic head of the recorder.

    摘要： A method for assuring a blazed condition in a DMD device used in telecommunications applications. By meeting certain conditions in the fabrication and operation of the DMD, the device can achieve a blazed condition and be very effective in switching near monochromatic spatially coherent light, thereby opening up a whole new application field for such devices. This method determines the optimal pixel pitch and mirror tilt angle for a given incident angle and wavelength of near monochromatic spatially coherent light to assure blazed operating conditions. The Fraunhofer envelope is determined by convolving the Fourier transforms of the mirror aperture and the delta function at the center of each mirror and then aligning the center of this envelope with a diffraction order to provide a blazed condition. The method of the present invention presents a formula for precisely determining the mirror pitch and tilt angle to assure that a blazed condition exists for a given incident angle and wavelength of near monochromatic spatially coherent light. Considerations for the special case, know as Littrow conditions, where the incident and the reflected light transverse the same path, are also given. This case is particularly attractive for fiber optic/telecommunication applications since the same optics can be used for incoming and outgoing (reflected) light.

    摘要： A system and method for reducing or eliminating speckle when using a coherent light source is provided. A refracting device comprising a birefringent material is positioned such that the refracting device intercepts the coherent light. The refracting device rotates thereby causing the ordinary and/or extraordinary beams to move. The human eye integrates the movement of the beams, reducing or eliminating laser speckle. The refracting device may include one or more optical devices formed of a birefringent material. Wave plates, e.g., a ½ wave plate, may be inserted between optical devices to cause specific patterns to be generated. Multiple optical devices having a different orientation of the horizontal component of the optical axis may also be used to generate other patterns. Furthermore, the refracting device may include an optical device having multiple sections of differing horizontal components of the optical axis.

    摘要： The present application describes a system and method for determining characteristics (e.g., exact band location, orientation and height and the spot shape and size of a single wavelength and the like) of an optical signal projected on a spatial light modulator. In an embodiment, images with sharper edges (i.e. clear boundary between ‘on’ pixels and ‘off’ pixels) on the spatial light modulator are used to obtain spectral information from a referenced broadband source. The spectral information can be used to determine the desired characteristics of optical signals projected on the spatial light modulator.
