    摘要: This invention provides an imaging optical system that can prevent blocking of a desired imaging light flux and prevent generation of unwanted ghost light. The imaging optical system includes: a first lens array that includes a plurality of lenses arrayed in a first direction and that forms an intermediate image of an object in a first section parallel to the first direction; a second lens array that includes a plurality of lenses arrayed in the first direction and that re-images the intermediate image of the object in the first section; and a light blocking member disposed between optical axes of adjacent lenses of the first and second lens arrays. At least one of the first and second lens arrays has a ghost light suppressing portion between adjacent lens surfaces. A width of the ghost light suppressing portion in the first direction is greater than a width in the first direction of the light blocking member.

    摘要: A scanner including a source of coherent or substantially coherent radiation, a radial hologon, a f lens and a target. Between the light source and the hologon there are means for forming radiation from the source into a collimated beam having an oblong cross-sectional shape and for directing the beam onto the hologon at a predetermined incident angle and with the long axis of the oblong cross-sectional shape of the beam radial of the axis of rotation of the hologon. Two prisms (56, 58) are provided between the hologon and the lens means for so modifying the cross-sectional shape of the beam (169, 191) that the spot at the target station has a selected shape and orientation. The prisms are mounted in an articulated mount (101) having adjustment (143) means, which allows rotation of the prisms so as to correct both bow in the scan line and incorrect placement of the scan line on the target. Such bow and incorrect placement could be created by a change of the wavelength of the radiation and by the pitch of the grating lines of the hologon being different to nominal.

    摘要: A light emitting device comprises a substrate (12); a first chip (14) incorporating a high density of lightemitting diodes (16), e.g. at up to 1000/inch, arranged in a substantially linear array and with electrical contacts (18), preferably extending alternately to opposite sides of the row; and one or a pair of IC chips (24) incorporating RAM and drivers for the diodes. The IC chips (24) are positioned alongside the LED chip (14) and interconnections are made by very fine wires (28) ultrasonically bonded to the contacts (22, 26). The hybrid circuit modules (10, 10a) can be assembled to give an extended diode array. The device (10) is utilised in image transfer systems where the diodes output to fibre optic filaments, micro-lenses or the like closely spaced above the diode chip (14) and having their output at or adjacent to a photosensitive medium. The system is particularly useful for high-speed, high-resolution phototypesetting.

    摘要: A two-dimensional optical scanning apparatus has at least one light source unit disposed on a plane which is perpendicular to a rotating axis. The light source unit may be a linear light source unit provided along a radial direction around the rotating axis, or an areal light source unit provided in a shape of a sector around the rotating axis. The light source unit rotates around the rotating axis to scan a light beam two-dimensionally. The light source unit may be substituted for a light receiving unit in a two-dimensional light receiving apparatus.

    摘要: A process and circuit arrangement are disclosed for regulating the luminous power of a laser diode in an optoelectronic point-by-point or line recording device for recording information on a recording material. A deviation ( DELTA l) is determined by comparing a luminous power set value to a measured luminous power real value. A fast regulator (2) generates a regulating current (IR) based on the deviation ( DELTA l). A slow regulator (3) with storage capabilities generates a working point regulating current (IA) that determines the working point on a laser diode characteristic curve and that is added to the regulating current (IR) to give the driving current (IT) of the laser diode (1). The luminous power set value and the slow regulator (3) are used during the switching-on periods of the laser diodes (1) at the beginning of the recording periods and during preliminary periods that precede the recording periods. The working point regulating current (IA) corrects the working point of the laser diode (1) during the preliminary periods and is kept constant during the subsequent recording periods. Oscillations of the luminous power (P) that may occur during the recording periods are only regulated by the fast regulator (2).
