Latest Patents

One of his latest patents is an optical coherence tomographic imaging apparatus. This invention involves emitting a first light beam and a second light beam with discrete wavelength bands from a light source unit, which then enter a light divider. The light divider separates each beam into measuring and reference light beams. The measuring light beams are directed onto a measurement target, and the reflected light beams are combined with the reference light beams to create interference signals. These signals are then used to obtain a tomographic image.

Another significant patent is for a super luminescent diode. This diode is designed to emit high-output super luminescent light with a central wavelength ranging from 0.95 μm to 1.2 μm. It features an n-type GaAs substrate and an optical waveguide path made of an InGaAs active layer. The design ensures a long element life and an undistorted beam cross-section, making it a valuable component in optical applications.
