Title: Innovations by Yoshinori Narutaki
Introduction
Yoshinori Narutaki is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of electro-optical technology, holding a total of 3 patents. His work focuses on enhancing measurement accuracy and efficiency through innovative designs.
Latest Patents
One of Narutaki's latest patents is an electro-optical distance meter. This device features a light-emitting element that directs light through a shutter to a target and captures the reflected light with a photodetector. The internal and external optical paths are continuously switched by the shutter at a predetermined time ratio, allowing for precise calibration of the distance being measured. This innovation reduces measurement time and enhances accuracy. In one design, the shutter consists of a disc with a C-shaped opening and an index for providing a reference signal. In another design, a liquid crystal switch is utilized for the shutter mechanism.
Another notable patent is equipment for measuring differences in elevation. This system employs a leveling pole with coded marks indicating height at unit intervals, along with a level that includes a telescope and an image sensor. The output signal from the sensor is decoded to display a digital height value. A plate glass is positioned in front of the object lens to vertically compensate the optical axis of the telescope. The inclination angle of the plate glass is used for interpolation between two adjacent coded marks, enhancing the accuracy of elevation measurements.
