| Abstract: | We report on simultaneous frequency domain optical-resolution photoacoustic and fluorescence microscopy with sub-µm lateral resolution. With the help of a blood smear, we show that photoacoustic and fluorescence images provide complementary information. Furthermore, we compare theoretically predicted signal-to-noise ratios of sinusoidal modulation in frequency domain with pulsed excitation in time domain.OCIS codes: (170.5120) Photoacoustic imaging, (180.2520) Fluorescence microscopy, (110.5125) Photoacoustics, (170.3880) Medical and biological imaging, (140.2020) Diode lasers |
