Dec 23, 2024 · We evaluate the performance of 4Pi-SIM by imaging various subcellular structures across different cell types with high fidelity. Furthermore, we demonstrate its capability by conducting...

Using two opposing objectives in a so-called 4Pi geometry doubles the available numerical aperture, and coupling this with interferometric detection has demonstrated 3D resolution down to 10 nm over entire cellular volumes.

Oct 1, 2024 · General Atomics '4Pi System has redefined fusion capsule analysis, enabling historic ignition at National Ignition Facility in 2022 and after.

Apr 1, 2022 · Herein, we review the recent progress in 4Pi nanoscopy, which provides a 3D, non-invasive, diffraction-unlimited, and isotropic resolution in transparent samples. This review includes both the targeted and stochastic switching modalities of 4Pi nanoscopy.

Dec 1, 2020 · Herein, we review the recent progress in 4Pi nanoscopy, which provides a 3D, non-invasive, diffraction-unlimited, and isotropic resolution in transparent samples. This review includes both the...

One is the 2pi / 4pi you're talking about, which just says how much of the sphere is covered by your detector. The other one is your detectors "response spectrum", which says which particle at what energy has what detection probability.

San Diego, June 3 – A new tool developed by General Atomics (GA) is enabling scientists to optimize the quality of targets used in Inertial Confinement Fusion (ICF) experiments. The system, known as 4Pi, has already led to improved experimental results and higher ICF yields.

Mar 13, 2011 · By splitting the fluorescence light into orthogonal polarization states, our 4Pi setup also facilitates the 3D nanoscopy of multiple fluorophores. Offering a combination of multicolor recording,...

In a 4Pi microscope of type C, the height and shape of the lobes of the effective PSF are strongly determined by the ratio between the excitation and the detection wavelengths.

4Pi Superresolution Microscopy Literature References. Taking advantage of dual juxtaposed objectives, 4Pi microscopy is able to converge the excitation illumination at a common focal plane to generate constructive interference that reduces …
