発明の名称 (英語) MEASUREMENT DEVICE
発明の概要(英語) The present invention expands the measurement band of a measurement device having a spectroscopic optical system, simplifies a control system for the measurement device, and reduces the cost of the measurement device. Provided is a measurement device for measuring the transmission characteristics or reflection characteristics of a sample to be measured, wherein: the measurement device is provided with a frequency comb light source for outputting comb light including a plurality of light modes having a constant frequency interval, a spectroscopic optical system that receives the comb light and decomposes the plurality of light modes in the comb light into individual frequencies, and a photodetector for detecting the intensity of at least one light mode from among the plurality of light modes extracted from the spectroscopic optical system; a single light mode having the intensity thereof detected by the photodetector passes through or is reflected by the sample to be measured, which is disposed between the comb light source output and the photodetector input; and the frequency interval between the comb light modes is larger than the optical frequency resolution of the spectroscopic optical system.
