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.

Differential photoacoustic microscopy technique

Optics Letters, 2013
Photoacoustic microscopy (PAM), whose image quality largely depends on the optical absorption of samples, provides endogenous information for structural and functional imaging. However, PAM technology in general can not provide edge enhancement imaging for absorbing objects.

Fast wavelet-based photoacoustic microscopy

Journal of the Optical Society of America A, 2021
A novel photoacoustic microscopy (PAM) structure, based on Haar wavelet patterns, is proposed in this paper. Its main goal is to mitigate the PAM imaging resolution and thus the time of its sampling process without compromising the image quality. Owing to the intrinsic nature of wavelet transform, this structure collects spatial and

Photoacoustic expansion microscopy of melanosomes

Optics Letters
Optical resolution photoacoustic microscopy (OR-PAM) is a hybrid imaging method for visualizing organelles due to the high spatial resolution and abundant optical contrast. Usually, OR-PAM employs high numerical aperture (NA) objectives and high-frequency ultrasonic detectors to resolve three-dimensional (3D) microstructures of cells.

Acoustic-spectrum-compensated photoacoustic microscopy

Optics Letters, 2020
Photoacoustic microscopy (PAM) can label-free image oxy- and deoxy-hemoglobin ( H b O 2 and Hb) concentrations in vivo, providing useful information for metabolic researches and diagnostic applications. Conventional PAM assumes a linear relationship between the photoacoustic amplitude

Translational Photoacoustic Microscopy

2015
Photoacoustic microscopy (PAM), combining the advantages of optical excitation and of acoustic detection, has been widely used for both structural and functional imaging with scalable resolution and penetration in biological tissues. In this chapter, we provide a detailed discussion on PAM in translational studies. We first summarize the principles and

Advanced intraoperative surgical photoacoustic microscopy

2014 11th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI), 2014
We developed an advanced intraoperative surgical photoacoustic microscopy (AISPAM) system by fusing a laser-scanning based optical-resolution photoacoustic microscopy (LS-OR-PAM) with 1064 nm pulsed laser, augmented reality device, and commercial surgical microscope. By sharing the same optical path of sample part in the LS-OR-PAM and microscope system,
