摘要： PURPOSE:To enable monitoring of primary light to be accomplished accurately and efficiently by monitoring the primary light used in image recording by using the primary light changing at the same ratio as said primary light. CONSTITUTION:The image signal being outputted from an image signal generator 14 is modulated by two different frequencies f1, f2 with modulators 17, 18, after which these are coupled in a coupler 19 and the coupled signal is applied as modulating signal 21 to an acousto-optic element 4. Thereupon, the inputting of the modulating light 21 and the radiation of a laser beam Lb cause the acousto-optic element 4 to emit 0 order light L0 and two lengths of the primary light L1, L2 corresponding respectively to the frequencies f1, f2 toward mutually different directions at different polarization angles. The primary light L1 forms images on a photoreceptor 10 and is monitored by using the primary light L2 changing at the same ratio as the primary light L1 and therefore monitoring of the primary light L1 may be performed accurately and efficiently.

摘要： PURPOSE:To detect minor flaw in object being examined and obtain position information of flaw at the same time, by detecting reflected light or transmitted light from the object being examined with a solid image sensor. CONSTITUTION:A laser beam 13 from a laser 12 is expanded by a beam expander 16 through mirrors 14, 15, and, after principal scanning with a rotating polyhedral mirror 17, is condensed onto the object being examined 19 by means of a condenser lens 18, and the reflected light therefrom is imaged on a solid image sensor 21 by means of an imaging lens 20. If there is an abnormal position in the object being examined 19, it is detected by the image sensor 21. Performing subordinate scanning by sending the object being examined 19 by the driving system 24, the rotating speed of the driving system 24 is detected by a position detector 25 to detect the subordinate scanning position of the object being examined, of which signal is applied to a signal controller 27. A photo sensor for synchronization 26 detects the scanning beam from the lens 23 at the principal scanning direction end part. Using the output signal thereof, the controller 27 synchronizes the image signal transfer pulse of the image sensor 21 with the scanning beam. The controller 27 causes the size and location of the abnormal position to be displayed in a display part 28, and the waveform is displayed in a CRT 29.
