Background, Motivation and Objective Majority of current studies on photoacoustic (PA) imaging are focused on the total signal magnitudes as the reflection of the macroscopic optical absorption by specific chemical contents at single or multiple optical wavelengths. Our recent research has demonstrated that the frequency domain power distribution of radio-frequency (RF) PA signals contains the microscopic information of the optically absorbing materials in the sample. In this research, we were seeking for the best method of systematically analyzing the PA measurement from biological tissues and the feasibility of quantifying tissue chemical and microstructural features for potential tissue characterization.
