Scanning light-field microscopy
Light field microscopy (LFM) is a scanning-free 3-dimensional (3D) microscopic imaging method based on the theory of light field. This technique allows sub-second (~10 Hz) large volumetric imaging ([~0.1 to 1 mm] ) with ~1 μm spatial resolution in the condition of weak scattering and semi-transparence, which has never been achieved by other methods. Just as in traditional light field rendering, there are two steps for LFM imaging: light field capture and processing. In most … WebNov 11, 2024 · 11.11.2024. Scientific Digest SNOM ( pdf 1.5 Mb) Scanning near-field optical microscopy (SNOM) enables studying a sample’s optical properties with resolution far beyond the diffraction limit. Sample fluorescence, light emission, transmission, scattering etc. can be mapped with the spatial resolution down to tens of nanometers.
