Title: Optical fiber sensor and liquid level sensor
Inventor: HAYASHI AKIHIRO
IPC: G01N21/41
Filed: 1988-05-06
Abstract: PURPOSE:To achieve a higher working efficiency and a small size of a sensor, by bending an optical fiber comprising a core section covered with a clad layer sharply to form a sensor section. CONSTITUTION:An optical fiber comprising a core section covered with a clad layer is bent sharply to form a sensor section S. There appear components of light that do not satisfy conditions of critical angle of propagation light at an interface between the core section and the clad layer. Moreover, out of the components of light, there appear components of light that do not satisfy conditions of critical angle of propagation light in the clad layer and a medium to be measured and hence, the components of light passing through any interface are incident on the medium to be measured, which causes a radiation loss at a bend part. As a result, the quantity of light (radiation loss) radiated to the medium to be measured varies with a change in refractive index of the medium to be measured. Thus, the determination of the radiation loss enables measurement of the density of the medium to be measured thereby enabling a higher working efficiency and a smaller size of a sensor.
