【発明の名称】半導体レーザアレイ記録装置
Document Type and Number:
Japanese Patent JP2908657
Kind Code:
B2
Abstract:
An optical recording apparatus comprises a laser diode array including a plurality of laser diodes for producing a plurality of laser beams in response to a drive signal indicative of an image, an optical system for scanning the laser beams on a surface of a photosensitive body, a beam splitting unit for splitting the laser beams produced by the laser diodes to form control laser beams; a driver for driving each of the laser diodes in the laser diode array, an optical detection unit provided for detecting the control laser beams, the optical detection unit including a plurality of photodetectors in correspondence to the laser diodes in the laser diode array in a one-to-one relationship, each of the photodetectors producing an output signal indicative of an optical power of the control laser beam incident thereto, and a control unit supplied with the output signals from the photodetectors in the optical detection unit for controlling the driver such that each of the laser diodes in the laser diode array produces the laser beam with a controlled optical power.
