Title: Hajime Kashida: Innovator in Optical Technology
Introduction
Hajime Kashida is a prominent inventor based in Nara, Japan. He has made significant contributions to the field of optical technology, holding a total of 6 patents. His work focuses on developing advanced devices that enhance measurement accuracy and efficiency.
Latest Patents
Kashida's latest patents include an optical object discriminating device. This device features a light projecting part that applies light emitted from a semiconductor light-emitting element to a measuring object. It also includes a light receiving part that captures reflected light from the measuring object. A polarization-state selector part is positioned between the light receiving part and the measuring object, allowing polarized light of a specified direction to pass through. The signal processing part processes the output from the light receiving part, measuring the intensity of light permitted by the polarization-state selector.
Another notable invention is an optical velocimeter, which aims for miniaturization and lower power consumption while accurately detecting the two-dimensional travel velocity of a measured object. This device consists of a light-emitting element, a diffraction grating, two light-receiving sections, and a signal processing circuit. Light emitted from the light-emitting element is branched by the diffraction grating into three light fluxes, intersecting at a detection point on the measured object. Scattered light from this point, frequency-shifted by the object's travel, is received by the two light-receiving sections, allowing for the detection of travel velocities in two directions.
