Label-Free Optical-Resolution Multispectral Photoacoustic Microscopy of Microvasculature Using Supercontinuum Laser

We have developed supercontinuum-laser-based optical-resolution multispectral photoacoustic microscopy which has the desirable properties of being compact, low-cost. The phantom and in vivo experiment results have demonstrated the photoacoustic microscopy system can accomplish label-free microvasculature imaging.
