ABSTRACT:
A laser-scanning fluoroscopy apparatus includes a laser light source of a plurality of wavelengths; a spectroscopic device for splitting laser beams according to wavelength; a focusing lens for focusing the split laser beams; a wavelength-selecting reflection device which includes a plurality of reflection sections disposed near the focal positions, spaced out at predetermined intervals in a split direction to reflect the laser beams with different wavelengths and a transmission section arranged adjacent to the reflection sections; a diffraction grating for combining the reflected laser beams; a scanning section for two-dimensionally scanning the combined laser beams; an objective optical system for focusing the scanned laser beams onto a tissue; and a photodetector for detecting fluorescence emitted from the tissue.
