Title: Liquid detection sensor
Inventor: NODA SADAO
IPC: G01F23/28
Filed: 2001-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a liquid detection sensor by which a liquid can be detected precisely, by a method wherein a detection region taking into account an influence due to air bubbles and drops of water to be stuck to the inside of a liquid housing container is ensured and an influence due to reflected light or the like by an outside wall is reduced. SOLUTION: When the liquid detection sensor is started, light is emitted from a projection optical fiber F1, and the sidewall 25 of the liquid housing container is irradiated with P-polarized light via a reflecting plate 28 by a polarizing filter 30. Since the P-polarized light is incident on the sidewall 25 at Brewstar's angle, it enters the sidewall 25 without being reflected by the outside face of the sidewall 25. The plane of polarization of the entered light is not retained, and the light is incident on the inner wall surface of the sidewall 25 as light containing the P-polarized light and S-polarized light. When a liquid coming into contact with the inner wall surface does not exist, the S-polarized light from among the incident light is passed again through the sidewall 25 so as to reach a light receiving part 24 via a light receiving window 29 and a reflecting plate.  When the liquid 31 (refractive index: n3) coming into contact with the inside wall surface exists, almost all of the incident light advances inside the liquid so as to reach the part 24.
