Modern imaging systems help scientists unveil the last secrets of the human body. Their understanding of cellular and molecular processes provides doctors and medical engineers with valuable insights for the development of new diagnostic and therapeutic procedures – many of them using the advantages of laser technology.
Classic (linear) optical spectroscopy is applied in analytics. This basic form consists of a broadband light source, a frequency-selecting element, and a detector.
In fluorescence analysis (e.g., in tissue diagnostics), the sample is excited using a specific wavelength.
