An Efficient Switching-Off of Coherent Anti-Stokes Raman
Web15 Dec 2024 · The narrowband operation of Sub-GHz networking enables transmission ranges up to several hundreds of meters indoors. There are three primary reasons for Sub-GHz superior range performance over 2.4 GHz applications. The rate of signal attenuation increases at higher frequencies; therefore, the 2.4 GHz signal weakens faster than a Sub … Web6 May 2013 · We report both sub-diffraction-limited quantum metrology and quantum enhanced spatial resolution for the first time in a biological context.

Subdiffraction-limited quantum imaging within a living cell
Web16 Aug 2012 · Abstract We theoretically investigate ground-state depletion for subdiffraction-limited spatial resolution in coherent anti-Stokes Raman scattering (CARS) … WebWe propose to use macroscopic Fourier ptychography (FP) as a practical means of creating a synthetic aperture for visible imaging to achieve subdiffraction-limited resolution. We … In astronomy, a diffraction-limited observation is one that achieves the resolution of a theoretically ideal objective in the size of instrument used. However, most observations from Earth are seeing-limited due to atmospheric effects. See more The resolution of an optical imaging system – a microscope, telescope, or camera – can be limited by factors such as imperfections in the lenses or misalignment. However, there is a principal limit to the … See more The Abbe diffraction limit for a microscope The observation of sub-wavelength structures with microscopes is difficult because of the Abbe … See more The limits on focusing or collimating a laser beam are very similar to the limits on imaging with a microscope or telescope. The only difference is that laser beams are typically soft-edged … See more • Rayleigh criterion See more There are techniques for producing images that appear to have higher resolution than allowed by simple use of diffraction-limited … See more The same equations apply to other wave-based sensors, such as radar and the human ear.
