    摘要： A confocal optical system is disclosed that utilizes fiber optic components in its construction. The system includes a light source, two detection units, an aperture and an optical element all optically coupled to a fiber optic coupler via optical fibers. In addition, a novel automatic focusing device is disclosed which utilizes chromatic aberration to maintain a target object in optimal focus. The device includes two light sources having different wavelengths of light, an optical element, an aperture, two detection units and a beam splitter. One light source is used to achieve initial focus and to illuminate the target object. The second light source is used to maintain the target object in optical focus. Light reflected off the target object is measured by one of the detection units. The magnitude of the light of the second wavelength measured by the detection unit is utilized to maintain focus. A second detection units is utilized to measure the intensities of the two light sources to yield normalized results. Further, a method of diagnosing an optical system is also disclosed. The method includes comparing a current set of readings of light against a set of reference readings taken at an earlier point in time. If the difference exceeds a predetermined threshold, a problem is indicated.

    摘要： A novel optical system operative to transfer, with high efficiency, optical power from a line source, such as a LDB, built from a plurality of individual light sources with different angular distribution in two orthogonal axis into a rectangular area with a particular aspect ratio and two different numerical apertures. The near field pattern of a LDB is imaged onto the plane of an SLM. The system utilizes light generated from an LDB having a plurality of individual light sources to illuminate a microlens array. The microlens array, consisting of a plurality of microlenses, functions to collimate the light from the LDB in the slow axis. An optical element adjacent the microlens array refracts the light in the fast axis. In the slow axis, the light from the microlens array is incident upon an optical element which focuses the light onto the SLM plane such that the light from each point light source illuminates the entire active pixel area of the SLM. An additional optical element focuses the light in the fast axis to generate the required spot image. The optical system of the present invention utilizes natural aberrations and/or artificial aberrations to decrease the sensitivity of the optical system to the smile phenomena exhibited by most laser diode bars.

    摘要： Apparatus, including a printing system, press, press components, and printing members for lithographic printing and other similar processes, is disclosed. The printing system for imaging printing members includes a plurality of infra red laser diodes coupled to a respective optical fiber for providing an output light beam, and a stationary telecentric lens assembly, that operates to image a printing member by exposure from ablative infra-red radiation. The printing members include a first substrate layer, with a second radiation absorbing layer over this first layer, for supporting an image ablated onto the printing member. A third surface coating layer is over the second layer. The third layer is substantially abdhesive to ink while the second layer has an affinity for ink opposite that of the third layer. Methods for imaging with the apparatus and for imaging the printing members are also disclosed.
