A team at South Korea's Pohang University of Science and Technology (POSTECH) has developed a way to process low-resolution label-free photoacoustic images into high-resolution virtually stained ...

In addition, both the pump and probe light beams are directly delivered through the same fiber for the excitation and detection of the photoacoustic signal, avoiding bulky free-space optics for ...

proposed a gas sensing technology named quartz-enhanced photoacoustic spectroscopy ... wave detection and producing a large piezoelectric signal under the same excitation conditions.

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2025.240275, discusses A highly sensitive laser gas sensor based on a four-prong ...

The miniaturized all-fiber photoacoustic spectrometer (FPAS) consists of a single optical fiber, a silica capillary, and an elastic membrane. The fiber's end facet and the membrane form a Fabry ...

Conversely, mid-infrared photoacoustic microscopy (MIR-PAM) allows for label-free imaging, preserving cell integrity. Yet, its reliance on longer wavelengths limits spatial resolution, making it ...
