Abstract:
1. A microscope device, comprising: a laser beam source that outputs illumination rays; a modulator disposed in front of the laser beam source and configured to separate the illumination rays output from the laser beam source into at least two portions, and to modulate at least one of the at least two portions of the illumination rays; objective lenses disposed ahead of the modulator and configured to guide the at least two portions of the illumination rays such that respective optical paths overlap each other on a specimen; a detection means for detecting feedback light rays generated by interference light occurring in a region where the respective optical paths overlap each other; and a control device configured to receive a signal from the detection means and control the modulator, wherein the specimen is irradiated with the at least two portions of the illumination rays, the detection means detects the feedback light rays emitted from the specimen based on the at least two portions of the illumination rays, optical paths of the at least two portions of the illumination rays between the respective objective lenses and a focal point are separated from each other so as not to overlap each other, the feedback light rays are fluorescent rays, and the detection means detects the fluorescent rays generated by the interference light, the detecting means comprises an optical detector and a band-pass filter, a signal is delivered to the band-pass filter from the optical detector, and modulations at given frequencies differing from each other are applied to at least two portions of the illumination rays, and intensity modulation varying at a sum of, or a difference between at least two frequencies is induced by the interference light occurring at a focal point on the specimen.
