the out-of-focus error of the sample which is caused by the offset of detected position can not be compensated, thereby restricting the improvement of the spatial resolution of the confocal Raman spectral imaging technology.
The confocal Raman spectroscopy has varied requirements for the size of detecting converging spot according to the research fields such as the detection of drug, gemstone identification, oil and gas exploration, chemical analysis and archaeology. However, the existing confocal Raman detection technology could not accurately control the size of the converging spot. As a result, the application of the confocal Raman spectral imaging technology in various fields may be constrained.
In the existing confocal Raman spectrometer, the Raman scattering light included in the scattering light of the sample collected by the system is extremely weak, whichsolidarity with their country as it came under attack after a Danish newspaper printed the controversial cartoons, including one that depicted the Islamic prophet Mohammed as wearing a turban shaped as a bomb. “Usually the Jews are always in the center of things, but here we feel we are part of the Danish population,” said Rabbi Bent Lexner, Denmark’s chief rabbi. Other newspapers across the world  in France, in Australia and in the United States  printed one or more of the cartoons. In France, the editorial director of France Soir, was fired after running at least one of the cartoons. At least one Israeli paper, the Jerusalem Post, also reprinted the cartoons. A German Jewish Web site, haGalil, got hacked after it posted some of the
