Introduction

Hideki Oka is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the field of optical encoders, holding a total of 3 patents. His work focuses on improving detection signals in optical systems, showcasing his expertise and innovative thinking.

Latest Patents

One of his latest patents is a diffraction-type optical encoder with an improved detection signal. This invention utilizes a collimated lighting system where an index scale is inclined toward a main scale by a predetermined value. This arrangement allows for the offsetting or integration of variations in the detection signal due to changes in the grating gap, thus avoiding dependence on the S/N ratio of the detection signal. Another significant patent is a reflection-type encoder that employs a diffusing light source. In this design, diffused rays from a point light source are focused by a condensing lens to create a secondary point light source positioned on a plane defined by the second gratings of the index scale. This innovation eliminates the need for a collimator lens, resulting in a more compact encoder design.
