Photoacoustic microscopy [PDF]
Laser and Photonics Reviews, 2013 AbstractPhotoacoustic microscopy (PAM) is a hybridin vivoimaging technique that acoustically detects optical contrast via the photoacoustic effect. Unlike pure optical microscopic techniques, PAM takes advantage of the weak acoustic scattering in tissue and thus breaks through the optical diffusion limit (∼1 mm in soft tissue).

Two octaves spanning photoacoustic microscopy [PDF]
Scientific Reports, 2022 In this study, for the first time, a Photoacoustic Microscopy instrument driven by a single optical source operating over a wide spectral range (475–2400 nm), covering slightly more than two octaves is demonstrated. Xenopus laevis tadpoles were imaged in

Sensitivity of photoacoustic microscopy
Photoacoustics, 2014 Building on its high spatial resolution, deep penetration depth and excellent image contrast, 3D photoacoustic microscopy (PAM) has grown tremendously since its first publication in 2005. Integrating optical excitation and acoustic detection, PAM has broken through both the optical diffusion and optical diffraction limits.

Integrated Photoacoustic and Fluorescence Confocal Microscopy [PDF]
IEEE Transactions on Biomedical Engineering, 2010 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 objective lens, intrinsically registered photoacoustic and fluorescence images are acquired in a ...
