Title: Heijiro Hirayama: Innovator in Optical Coherence Tomography
Introduction
Heijiro Hirayama is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of optical coherence tomography, holding a total of 3 patents. His work has advanced the technology used in medical imaging and diagnostics.
Latest Patents
Hirayama's latest patents include an optical coherence tomography apparatus and measurement method. This apparatus generates a full-color optical coherence tomographic image. The image generation unit features a correction processing unit that calculates an attenuation-related value. This value pertains to the attenuation of signal intensity of the interference light of three colors: red, green, and blue. The unit corrects the signal intensity of a second depth region based on this value, allowing for the generation of a full-color optical coherence tomographic image.
Another significant patent involves a light penetration depth evaluation method and a performance test method using this evaluation method. This method utilizes an optical tomography technique that splits low coherent light into sample light and reference light. The sample light is emitted to a measurement target in a line shape, generating interference light by superimposing reflected light. The two-dimensional spectroscopic tomographic image of the measurement target is acquired through spectroscopic detection and frequency analysis. This innovation allows for the evaluation of the penetration depth of the sample light based on the acquired image.
