Abstract

Photoacoustic imaging technology using multi-wavelength can achieve functional image that provide information about a singularity in an image target. We developed a wavelength tunable light source pumped by few tens kHz pulsed laser with 532 nm wavelength for single scan functional photoacoustic imaging. The laser has individual output pulses with about 200 nsec time delay between the original 532 nm pump pulse and the wavelength tunable pulse. By using the ping-pong pulse output, we have make enable to obtain a functional photoacoustic image in a single laser scanning and demonstrated functional photoacoustic microscopy imaging to show a mouse activity.
