Abstract
A Raman scattered light measurement system includes a Stokes light generation unit configured to generate broadband Stokes light, a pump light generation unit configured to generate narrowband pump light, and a wavelength change unit configured to change a center wavelength of the pump light in two different wavelengths.
Claims12
A Raman scattered light measuring system comprising;
- a Stokes light generator configured to generate Stokes light with a broad band;
- a pump light generator configured to generate pump light with a narrow band;
- a wavelength changing unit configured to change center wavelength of the pump light in two different wavelengths;
- a measurement device configured to measure a signal intensity at each frequency of reflected light obtained by irradiating a sample with the pump light and the Stokes light to obtain a signal intensity measurement value;
- and
- a calculation device configured to calculate a difference between the signal intensity measurement values for each frequency before and after the wavelength changing unit changes the center wavelength of the pump light.
