発明の名称 (英語) MEASURING DEVICE AND MEASURING METHOD
発明の概要(英語) An objective of the present invention is to provide a measuring device for which the need for adjustment of a coherence optical assembly when changing a molecule to be measured is eliminated. A measuring device (1) comprises: a light source unit (10) which emits a pump beam (PP), a Stokes beam (ST), and a signal beam (SG); a light projection unit (20) which projects the pump beam (PP) and the Stokes beam (ST) upon a subject (S); a light modulation unit (30) which modulates the wavelength of the signal beam (SG); a first light detection unit (50) which detects coherent light between the wavelength-modulated signal beam (SG) and an anti-Stokes beam (AS) from the subject (S); a second light detection unit (52) which detects coherent light between the signal beam (SG) and the wavelength-modulated signal beam (SG); and a signal detection unit (60) which detects, from the signal from the first light detection unit (50), a component which is 90° out of phase with the signal from the second light detection unit (52). An optical parametric oscillator (12) of the light source unit (10) further comprises two nonlinear optical crystals which rotate to incline at the same angle in opposite directions with respect to the optical path.
