Abstract
A method and a method for determining flow speed based on photoacoustic imaging or sensing. The method includes receiving multiple photoacoustic signals from a sample in response to transmission of multiple laser pulses of different wavelengths to the sample, and processing the photoacoustic signals based on a flow model that relates photoacoustic signals with flow speed to determine a flow speed of a liquid flow in the sample.
