Previous photoacoustic flow measurements have been demonstrated with various modalities including Doppler frequency shift measurement from intensity modulated continuous laser wave and pulsed photoacoustic Doppler cross- correlation from nanosecond laser pulse. Here, we propose and demonstrate a new type of photoacoustic Doppler velocimetry based on a hybrid approach: we applied a supercontinnum laser source with picosecond pulse and 40 MHz repetition rate, and then use electo-optic modulator to modulate the intensity at 1 MHz. This method can potentially improve the signal to noise ratio due to pulse excitation of photoacoustic signal, and at the same time to achieve the high resolution of Doppler frequency shift due to the intensity modulation. With this method, we measured the moving speeds of various samples at the range of 0.1-1.6mm/s and obtained accurate results. The extra advantage of using supercontinnum laser pulses is that the spectral range can be chosen by using spectral filter thus to realize the multispectral measurement. To demonstrate this, we set the spectral filter working at five ranges at 500nm, 550nm, 600nm, 650nm, 700nm center wavelengths all with 100nm spectral width and measured different materials as moving targets fixed on the translation stage, including such as graphene thin layer, black tape, red and black dyed microspheres.
