Abstract
Official abstract text for this publication.
Disclosed herein is a fiber optic sensor using a transmissive grating panel and a mirror, in which displacement resulting from a temperature change in the external environment or a behavioral change in an object to be measured is measured using a transmissive grating panel, a reflection mirror and an optical fiber, and then enables various measurements to be taken of the temperature change in the external environment and the behavioral change (displacement, pressure, vibration or acceleration, etc.) in the object on the basis of the measured displacement.
First claim
Opening claim text (preview).
What is claimed is: 1. A fiber optic sensor using a transmissive grating panel and a mirror, comprising: response means for changing displacement in response to a temperature change in an external environment or a behavioral change in an object that is to be measured; a transmissive grating panel provided on an end of the response means, and including transmissive surfaces and non-transmissive surfaces arranged at predetermined pitches in a grating pattern, each of the transmiss…
