Abstract

PURPOSE:To vary the light distribution of a medium to be measured and to increase the quantity of variation of photodetection by interposing a body with a specific refractive index at the periphery of a reflection body and refracting light by the border surface between the medium to be measured and interposed body. CONSTITUTION:Light B emitted by an end surface of an optical fiber 2 having a specific angle to an axial right-angled surface is refracted by the medium M present at the periphery of the projection end of the optical fiber. The light distribution of the refracted light varies with the refractive index of the medium. Further, the refracted light is refracted by the border surface between the medium to be measured and the body 4 which is provided previously and has a refractive index no, reflected by the reflecting surface of the reflection body 6 to further travels, and refracted again by the border surface between the medium to be measured and the body 8 with the refractive index no, so that the light is photodetected by an optical fiber 12 for photodetection. The light distribution is therefore emphasized by the refractive index (n) of the object medium in every operation.
