Imaging Apparatus for Infrared Rays Nonlinear Molecular Vibrational Microscopy |
摘要 |
The present invention relates to an imaging apparatus for infrared rays nonlinear molecular vibrational microscopy. The imaging apparatus comprises a pump beam source for generating an infrared pump beam; a probe beam source for generating a probe beam; a beam combiner which synchronizes temporally and overlaps spatially the pump beam and probe beam on the same axis; a scanner for two-dimensionally scanning the combined pump beam and probe beam; a first optical focusing system for focusing the scanned pump beam and probe beam on a local point of the sample; a first collecting optical system for collecting the beam of which phase is shifted by interaction with the sample and forming a parallel beam; a first dichroic beam splitter for removing the infrared pump beam out of the parallel beam and splitting the probe beam of which phase is shifted; a reference interferometer for splitting a part of the probe beam out of the beams scanned by the scanner and generating a reference probel beam; an interferometric beam combiner for combining the probe beam having the shifted phase and the reference probe beam; a photodetector for detecting an intensity of a molecular vibrational beam signal from the combined probe beam; and a data analyzer for acquiring the detected signals and extracting a spectrospcopic information corresponding to the strength of molecular vibrational coherence of the sample. |
