Title: Noritsugu Watanabe: Innovator in Road Surface Surveying

Introduction

Noritsugu Watanabe is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of road surface surveying through his innovative patent. His work focuses on enhancing the accuracy and efficiency of road surface assessments.

Latest Patents

Watanabe holds a patent for a "Method for mobile survey of road surface." This invention involves scanning a road surface illuminated by sunlight with a laser beam at right angles to the direction of travel. The intensity of the laser beam is modulated with a predetermined frequency. The reflected laser beams are received and optically filtered to eliminate light frequencies outside that of the laser beam. The filtered laser beam then strikes multiple beam position sensing elements, generating respective electrical signals. These signals are multiplexed and electrically band-pass filtered, with the center frequency of the filtering coinciding with the modulation frequency of the laser beam. This innovative method enhances the precision of road surface surveys.
