MEASUREMENT DEVICE AND MEASUREMENT METHOD

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.

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