    Abstract: PROBLEM TO BE SOLVED: To provide a color sensing system for determining color characteristics of an object. SOLUTION: In this color sensing system, a peripheral receiver optical fiber/element 7 is provided apart from a central light source optical fiber/element 5 to receive and measure the light reflected from surface of the object 20. Light from the peripheral fiber optics 7 passes through various filters. The peripheral receiver optical fiber 7 is used to determine information on height and angle of a probe 1 to the measuring object 20. Under control of a processor, color measurement is performed at the given height and angle. Configurations of various color spectrophotometers are disclosed. Also data on translucence, fluorescence property and/or surface structure can be acquired. Further an operator can be led to use this system by being supplied with audio feedback. The probe 1 also may have either a freely-attachable/detachable or shielded tip for inhibiting contamination. COPYRIGHT: (C)2006,JPO&NCIPI

    Abstract: PURPOSE:To obtain a sensor having a high sensitivity, whose structure is simple and which can be manufactured easily, by polishing optically a pipe so that two optical fibers inserted and fixed in parallel in a containing pipe have an apex angle in such a plane as they are symmetrical to each other. CONSTITUTION:An emitting optical fiber 2 for emitting a light for sensing, and an incident optical fiber 3 for photodetecting a light reflected by an object to be measured are inserted and fixed in parallel in an optical fiber containing pipe 1. Also, the end face of the containing pipe 1 fixed the optical fibers 2, 3 are optically polished diagonally so that the shortest distance between the two optical fibers is divided into two equal parts and also they have an apex angle in a plane being parallel to both the optical fibers. As a result, a refractive index (air 1) of the periphery of the fibers is smaller than a refractive index (for instance, 1.46) of a core of the optical fiber, therefore, a light emitted from the fiber 2 is refracted in the center line direction of two optical fibers, an intensity of a light which is made incident on the fiber 3 becomes larger than the case of a conventional vertical polishing, and accordingly, a sensitivity of a sensor also becomes high.
