摘要： A measurement device includes: a light source that generates a pump beam and a Stokes beam; a pulse stretch section that stretches the pulse of the pump beam so that the pulse width of the Stokes beam is shorter than the pulse width of the pump beam; an optical splitter that splits the Stokes beam into two beams; an optical scan section that scans a subject with the pulse-stretched pump beam and one of the two beams split by the optical splitter; a first optical detector that detects an anti-Stokes beam from the subject; a second optical detector that detects an interference beam of the other of the two beams and the Stokes beam reflected by the subject; and a signal processing section that performs an image generation process based on a detection signal from the first optical detector and a detection signal from the second optical detector.
