Title: Teruo Hosokawa: Innovator in Optical Technology
Introduction
Teruo Hosokawa is a notable inventor based in Sakai, Japan. He has made significant contributions to the field of optical technology, particularly in the development of optical filters for color television cameras. With a total of two patents to his name, Hosokawa's work has had a lasting impact on the industry.
Latest Patents
One of Hosokawa's latest patents is an optical low-pass filter. This innovative filter is designed in the form of a rectangular wave phase grating, which includes at least two sets of parallel phase retardation laminae. The laminae in each set are positioned at an angle to those in the other set. This optical filter is utilized in systems equipped with color-encoding filters, such as single tube color television cameras. It effectively attenuates high-frequency components of an image, ensuring that the degree of blur exceeds the value calculated from the grating period of the color-encoding filter. Another significant patent is for a color television camera optical system. This system minimizes color shading, moire patterns, and color beats by incorporating a phase grating low-pass filter, a color encoding filter, and a lenticular lens member. These components are strategically oriented to reduce interference between the color encoding filter and striped patterns in the viewed object.
