Title: **Innovative Contributions of Atsushi Doi in Optical Measurement Technology**

Introduction

Atsushi Doi, an esteemed inventor based in Tokyo, Japan, has made significant contributions to the field of optical measurement technology. With a total of five patents to his name, Doi's inventions focus on advanced imaging techniques that enhance the understanding of light behavior in various samples, and improve image acquisition methods.

Latest Patents

Among his latest patents are the "Point-Spread-Function Measurement Device and Measurement Method" and the "Image Acquisition Apparatus and Image Acquisition Method". The point-spread-function measurement device consists of a scanner that precisely scans two illumination light beams originating from a dedicated light source. This device includes an illumination optical system that radiates the scanned beams onto a sample, allowing for fine-tuning of their relative positions. A detection optical system captures the signal light produced at the overlapping area where the beams converge, and a calculator processes this information to derive the point spread function based on the detected signal light and the relative position of the beams.

Additionally, the image acquisition method utilizes a pulsed illumination beam that is focused on a sample while being scanned. This method detects signal light generated from a non-linear optical process and compiles images based on this information. Notably, it allows for the separation of in-focus signal light from out-of-focus signal light, enhancing the clarity and relevance of the captured images.
