Introduction

Atsushi Morosawa is a notable inventor based in Kasugai, Japan. He has made significant contributions to the field of optical coherence tomography, holding three patents that showcase his innovative approach to technology.

Latest Patents

Morosawa's latest patents include an optical coherence tomography system and method that utilize a tunable light source for varying emission wavelengths. This system employs an optical interferometer and a reflector positioned at a measurement location. The light interference signal is A/D converted at regular time intervals, and data points at peak and bottom timings are calculated using a least-squares method. An approximate equation is derived through polynomial approximation, allowing for the calculation of a sequence that includes the number of exponentiation of 2. By placing a measured target at the measurement position, the necessary data for FFT is calculated from the measured data at each timing. This process enables the acquisition of a tomogram with high resolution and sensitivity. Additionally, his tunable fiber laser light source features an optical fiber loop with a gain medium and optical circulators. The system includes collimating lenses and a polygon mirror that rotates to change the selected wavelength according to the incident angle to a diffraction grating, enhancing selectivity.
