Integrated Photoacoustic and Fluorescence Confocal Microscopy [PDF]
IEEE Transactions on Biomedical Engineering, 2019 We have developed a dual-modality imaging system by integrating optical-resolution photoacoustic microscopy and fluorescence confocal microscopy to provide optical absorption and fluorescence contrasts simultaneously. By sharing the same laser source and

Slow-sound photoacoustic microscopy [PDF]
Applied Physics Letters, 2013 We propose to enhance the axial resolution of photoacoustic microscopy (PAM) by reducing the speed of sound within the imaging region of interest. With silicone oil immersion, we have achieved a finest axial resolution of 5.8 μm for PAM, as validated by ...
