Title:
MEASUREMENT DEVICE AND SENSOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/080415
Kind Code:
A1
Abstract:
The present invention provides a measurement device that uses stimulated Brillouin scattered light, said device not requiring linear frequency sweeping. Provided is a measurement device that measures the gain spectrum of stimulated Brillouin scattered light in an object to be measured, said device being provided with: a first comb light generator that generates a first comb light and inputs said light to one end of the object to be measured; a second comb light generator that generates a second comb light of which the reference frequency is shifted, relative to the first comb light, only by the Brillouin shift frequency of the object to be measured, and which has a different frequency interval, and inputs the second comb light to the other end of the object to be measured; and a measuring apparatus that measures the spectrum of the stimulated Brillouin scattered light output from the object to be measured.
