Title: Photo-detector
Inventor: HATSUTORI KATSUJI
IPC: G08C23/04
Filed: 1978-11-14
Abstract: PURPOSE:To prevent erroneous operation due to electric noise, etc., by having at least a part of a light medium supported by a deformed body, at the time of optical coupling between 2 optical fibers, and converting variation of physical value to a variation of optical coupling value between the optical fibers. CONSTITUTION:A penetration type detector is formed in such a mechanism that a movable light medium 3, such as a 1/2 cycle self-concentrating lens, is arranged between optical fibers 1 and 2 which are positioned opposite to each other. In normal condition, optical coupling between the fibers 1 and 2 is achieved at a low loss rate. And a light medium 3 is supported by a movable supporting body 4 consisting of a spring-like body or a plate-like springing body. When this light medium 3 is shifted upwardly or downwardly by some action or other, a light radiated from the left-side optical fiber 1 does not pass through the center of the light medium 3, and therefore, the light is not concentrated in the right-side optical fiber 2 and the optical coupling efficiency is thus deteriorated. And therefore, by matching shift of the light medium 3 with temperature, humidity and pressure, etc., variation of various physical values can be converted directly to coupling effeciency of the optical fibers.
