Abstract
The present disclosure relates to a divided-aperture laser differential confocal LIBS and Raman spectrum-mass spectrum microscopic imaging method and device. In the present disclosure, the divided-aperture differential confocal imaging technology is combined with the spectrum technology and the mass spectrum detecting technology, high-spatial resolution form imaging is performed on a sample by utilizing a minute focusing spot of a divided-aperture differential confocal microscope processed by using the super-resolution technique, a mass spectrum detection is performed on charged molecules or atoms in a sample microzone by using a mass spectrum detecting system, a microzone spectrum detection is performed on spectrum excited by the focusing spot of a divided-aperture differential confocal microscope system by using a spectrum detecting system, and high-spatial resolution and high-sensitivity imaging and detection of complete composition information and form parameter of the sample microzone are implemented by using complementary advantages and structural fusion in laser multi-spectrum detection.
