The feasibility of diagnostic imaging and tissue characterization based on a new contrast realized by dual-pulse photoacoustic measurement was studied. Unlike current photoacoustic methods which are mostly focused on the measurement of tissue optical absorption, this contrast revealed by a dual-pulse laser excitation process takes advantage of the temperature dependence of the Grüneisen parameter of tissue. The first laser pulse heats the sample and causes a temperature rise in the target tissue, which leads to a change of th
