Simultaneous multicontrast OR-PAM from single laser source

(SPIE--International Society for Optics and Photonics) Optical-resolution photoacoustic microscopy (OR-PAM) can be used for live, multicontrast functional imaging, but the limited wavelength choice of most commercial lasers and the limitations of the existing scanning methods have meant that OR-PAM can obtain only one or two different types of contrast in a single scan. Lidai Wang and his research team at City University of Hong Kong recently developed a multiwavelength OR-PAM system based on a single laser source.
