Title: Yasuaki Kasai: Innovator in Optical Technologies
Introduction
Yasuaki Kasai is a prominent inventor based in Saitama, Japan, known for his significant contributions to optical technologies. With a total of 17 patents to his name, he has made remarkable advancements in the field of optical-fiber scanning and illumination apparatuses.
Latest Patents
Among his latest patents are an optical-fiber scanner, an illumination apparatus, and an observation apparatus. The optical-fiber scanner includes an optical fiber and a body fitted on the basal-end side of the optical fiber. It features piezoelectric elements that cause the optical fiber to vibrate, along with a securing portion that positions the body farther away from the piezoelectric elements. The body is designed with a columnar portion made of elastic material, which has a through-hole for the optical fiber, and a distal-end portion that supports the optical fiber in a fitted state. This distal-end portion has a rotator shape, with a cross-sectional area that gradually decreases toward the distal end of the optical fiber.
The scanner unit consists of a tubular elastic part with marks outside a prescribed bonding region on its outer surface. A piezoelectric element is bonded to this region, which includes a piezoelectric body with two opposing electrode faces. Each face has distinct marks, and the mark on one electrode face matches the mark outside the bonding region when the piezoelectric body is properly bonded.
