    Abstract: A method and an apparatus for making a moving body of material (26). The method includes the steps of directing at the moving body a high energy density beam (46,58), concentrating the beam so as to produce an illuminated spot at a location on or within the moving body, and moving the spot in accordance with the resultant of two components of movement, the first component being equal to the velocity of the moving body and the second component being relative to the moving body, so as to create a mark of a predetermined shape. In a preferred embodiment, the apparatus includes at least one movable galvanometer mirror (68,70) capable of moving the spot in accordance with the resultant of the two components.

    Abstract: An apparatus and method are disclosed for improving the recognition of reference data in a laser writing process, by storing the locations of chip topography situated along the scan raster in a memory. Using an entry code (reference mark) to provide synchronization of the laser beam and the chip topography, the digital signal coming from the detector of the scanning laser beam is checked for accuracy against the stored pattern. A synchronous correlator circuit is used to provide a corrected output based on the stored information and the actual detected signal which is then used to control the operation of the laser pattern generator. Incorrect tracking of the laser pattern generator due to defects in the scanned surface can thus be reduced or eliminated. Due to this improved recognition of surface reference points, smaller geometries can be used.

    Abstract: Display devices utilize thermotropic materials for recording and displaying information. The display devices incorporate a thermochromic film disposed between a pair of electrically conductive plates, one of which is transparent. Reflectivity of the film is altered by selectively changing the temperature of discrete portions of the film, and hysteresis in the thermochromic material is relied on to retain the information stored in the film for as long as it is needed. The electrically conductive plates may be used as one means to selectively heat the film so as to enhance a thermally generated image. Also disclosed are methods for changing information recorded in such displays.

    Abstract: A device is described in which amplified spontaneous emission from a high-gain laser medium illuminates an object through an optical system that also serves to collect the reflected or scattered light from the object and return it through the laser medium to form a highly amplified image. By modification of the optical system and control of the gain factor, the invention can be adapted for various uses including projection or etching of the amplified image on a substrate.
