In trials, POSTECH applied its system to photoacoustic images of human cardiac fibroblasts, and compared the results to corresponding CFM images. The results were "qualitatively and quantitatively ...

This isn’t the first time I’ve written about MIT’s photoacoustic work. They’ve used it for spectroscopy that can detect gasses at a distance. Of course, if you are willing to allow a ...

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 ...

Huang proposes combining two promising imaging techniques – photoacoustic microscopy and dual-comb spectroscopy – to establish the first dual-comb photoacoustic microscopy for deep- tissue ...

Laser Induced Breakdown Spectroscopy and Photoacoustic Spectroscopy for detection of volatile organic compounds, explosives, chemical and biological toxins for counter-terrorism, environmental ...

A new method for real-time detection and identification of very low concentrations of gases adds coherent control to quartz-enhanced photoacoustic spectroscopy, which uses a quartz tuning fork to ...
