<p>PURPOSE: To obtain an optical sensor device where no reflection wave enters a light reception device by providing a analyzer, a light reception device, a first light reception side optical waveguide body, and a second light reception side optical waveguide body at the downstream of a photosensor. CONSTITUTION: A photosensor device has a first radiation side optical waveguide body 3, a second radiation side optical waveguide body 14, a light radiation device 2, a polarizer 5, and a photosensor 1. Then, the sensor 1 changes the state of the polarization of polarization light beams being supplied as a function of physical quantity that is operated on the sensor and supplies sensor light beams formed by the polarization light beams. The device has an analyzer 7 for separating each sensor light beam into two linear polarization light reception measurement beam and a light reception device 12 for forming an electrical signal from light reception side light beams to determine physical quantity by an evaluation circuit 13. Further, it has a first light reception side optical waveguide body 9 and a second light reception side optical waveguide body 11 for supplying light reception side beams to the device 12.</p> |
