Introduction

Kazuhiko Ohnishi is a notable inventor based in Himeji, Japan. He has made significant contributions to the field of image reproduction technology, particularly through his innovative patent related to laser beam stabilization.

Latest Patents

Ohnishi holds a patent for an "Apparatus for stabilizing beam for exposure." This invention focuses on stabilizing a laser beam used for exposure in image-reproducing apparatuses. The apparatus effectively controls the beam using image signals obtained from scanning the original beam. The laser beam is modulated by an ultrasonic light modulator and branched into two beams by a half mirror. One beam is utilized for exposing photosensitive material, while the other serves as a negative feedback signal. This feedback is integrated with the image signal, significantly improving the linearity between the exposing beam and the image signals. Consequently, the stability of the exposing beam is enhanced.
