Abstract

PURPOSE:To obtain a small, light and dependable detector, by which an external change can be effectively converted into an optical signal, by utilizing the total reflection of the self-focusing type lens to the detector. CONSTITUTION:The total reflection mirror 9 is attached to one end face of the semicylindrical self-focusing type lens 8, the input-output of light is performed by the use of one optical fiber 10. The liquid crystal 12 the scattering characteristic of which is changed by temperature is placed on the cut face 11, scattered light depending on the external temperature, which is from the light 13 emitted from the optical fiber 10, is received by the liquid crystal 12, the light output 14 from the optical fiber is changed by temperature to make the device a temperature detector. Moreover, it can be applied to the detection of the refractive index and ultraviolet rays.
