摘要： An imaging apparatus includes a laser to generate a single-mode laser beam of energy, a multichannel spatial light modulator (SLM) accepting a plurality of modulating signals, and a beam multiplier between the radiation source and the SLM. The multiplier accepts the beam and generates from that beam a plurality of beams directed onto the SLM. The beams from the beam multiplier illuminate the active region of the SLM such that the SLM generates a plurality of modulated beams modulated according to the modulating signals. An optical subsystem is located between the SLM and an imaging plane including at least one optical element focusing the modulated beams onto the plane on which recording medium is placed to permanently mark the recording medium in response to incidence of such imaging radiation. Each beam from the SLM is substantially single-mode such that the optical subsystem can be designed using diffraction-limited optics.

摘要： A light beam position detecting device detects the passage positions of a plurality of light beams for scanning the surface of a photosensitive drum. The light beam position detecting device has a sensor pattern for generating an output which is continuously changed in a wide range with a variation in the passage position of the light beam in a sub-scanning direction perpendicular to a main scanning direction of the light beam. The sensor pattern precisely detects the relative scanning position of the light beam in a wide range. The passage positions of the plurality of light beams for scanning the surface of the photosensitive drum are controlled to a preset position based on the output of the sensor pattern.
