Title: Optical wave guide type temperature sensor
Inventor: MEGATA NAOYUKI
IPC: G01J5/00
Filed: 1986-03-18
Abstract: PURPOSE:To obtain a temperature sensor having high reliability, by providing only one optical guide among two Y-branched optical guides to the area having high electric field intensity of a substrate having pyroelectric effect and electrooptic effect. CONSTITUTION:By surrounding the outer peripheries of a substrate 6 and an insulating film 11a by a metal film 12, charge of inverse polarity is induced in the metal film 12 by the charge generating on the surface of the substrate 6. Therefore, an electric field is generated in the insulating film 11a between the surface of the substrate 6 and the metal film 12. However, in the interrupted part 13 of the metal film 12, the electric field formed by the charge on the surface of the substrate 6 passes through the optical wave guide 9 in the substrate 6 to form an area 7 having high electric field intensity. As mentioned above, only one of two wave guides after Y-branch generates the change in electric field intensity by the change in temperature and a refractive index changes by electrooptic effect. Therefore, by detecting the luminous intensity of light beams emitted from both optical wave guides 9, 10 and synthesized, temperature can be measured.
