Light-sheet microscopes with an extended depth of field (EDOF) offer a simple but powerful route toward fast volumetric imaging. However, methods for EDOF typically result in a loss of signal-to-noise ratio. Here, we propose a parallelization strategy as a simple solution. By illuminating multiple acoustically generated light sheets at...

We propose a novel light-sheet microscope, capable of high-speed volumetric imaging with high contrast and signal-to-noise ratio. The working principle is founded on extending the depth-of-field and enconding the illumination with multiple light-sheets.

The GAF3 domain of the cyanobacteriochrome Slr1393 from Synechocystis sp. PCC6803, binding phycocyanobilin as a chromophore, shows photochromicity between two stable, green- and red-absorbing states, characterized by relatively high photoconversion yields. Using nanosecond-pulsed excitation by red or green light, respectively, and suitable cw...

he photoacoustic effect (PA) is a physical phenomenon based on the emission of sound waves following light absorption in material samples. The photon absorption and subsequent non-radiative depletion of the chromophores rapidly rises the temperature within the sample, increasing the pressure and inducing a thermoelastic expansion, leading to...
