In photoacoustic imaging, photonic energy from a short non-ionizing laser
pulse is absorbed and converted into heat, leading to transient thermoelastic
expansion and thus wideband ultrasonic energy is produced. The generated
ultrasonic is detected by an ultrasonic transducer and then analyzed to
I will present our recent achievement on the superresolution photoacoustic
microscopy beyond the optical diffraction limit in collaboration with California
Institute of Technology and on developing resolution targets and fluence
phantoms and standards to enable quantitative photoacoustic imaging.
