Title: Innovations of Tatsuo Itou

Introduction

Tatsuo Itou is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of optical measurement technology. With a total of 2 patents, his work focuses on methods for detecting minute displacements.

Latest Patents

One of his latest patents is a method of measuring a minute displacement. This method involves the emission of two light beams with different polarizing directions from a light source. The beams are diverged by a lens and pass through a beam splitter towards a separating prism. After passing through the prism, the beams are separated into first and second measuring beams, which are then focused on spaced reflecting surfaces. The reflected beams enter photodetectors, providing signals indicative of the probe's minute displacement.

Another significant patent is a minute displacement detector using optical interferometry. This device includes a laser beam source and a diffraction grating that separates the laser beam into multiple components. A filter shields all but two beam components of primary order. A wavelength plate varies the polarized state of one of these components. The focused beam components are reflected from reference and displacement planes, and a photosensor detects the interference of these components.
