Document Type and Number:
Japanese Patent JP2007071613
Kind Code:
A
Abstract:

To provide an optical fiber pressure sensor which has a simple constitution and is manufacturable inexpensively; and also to provide a pressure detection device.

The optical fiber pressure sensor for determining a pressure from an optical loss of an optical fiber 1 by applying a local bending corresponding to the pressure to the optical fiber 1 is equipped with a bolster member 2 for supporting the optical fiber 1, and a pressing member 3 for pressing the optical fiber 1 onto the bolster member 2 and applying the local bending to the optical fiber 1. The bolster member 2 is supported by a base member 4, and the pressing member 3 is arranged so as to be pressed by a pressure transfer member 5 whose position is displaced to the base member corresponding to the pressure.
