WebIR-PHI spectra at a given point were obtained by measuring the IR-PHI response as a function of the IR laser wavelength. Spatially-resolved emission spectrum measurements. These measurements were performed after IR-PHI scans. The 532 nm laser was used as the excitation source for emission spectra measurements. Samples were raster scanned over ...
Far-field midinfrared superresolution imaging and …
WebIR microscopy/spectrsocopy is an optimal tool for obtaining chemical-specific information of samples without the need for exogenous labels. However, conventional far-field imagining methodologies are diffraction limited in the IR with effective spatial resolutions of >5 μm. WebDec 8, 2024 · IR-PHI has a spatial resoln. of ∼300 nm and can det. the chem. identity, morphol., and quantity of MNPs in a single anal. with high sensitivity. Specimens are supported on CaF2 coverslips under ambient conditions from where we (1) quantify MNPs from nylon tea bags after steeping in ultrapure water at 25 and 95°C, (2) identify MNP … can cats eat raw scallops
Super-Resolution Far-Field Infrared Imaging by ... - ResearchGate
WebInfrared photothermal heterodyne imaging (IR-PHI) is an established all-optical, table-top approach for conducting super-resolution mid-infrared microscopy and spectroscopy on submicrometer-sized particles. The instrument’s capabilities are highlighted by its ability to operate in spectroscopically-crowded environments. WebThe phi instruction takes a value input for each basic block which can reach the basic block in which this phi instruction is placed. So for each incoming branch, there is a value. The phi instruction is an artificial instruction which allows the IR-code to be in SSA form. class ppci.ir.Undefined (name: str, ty: ppci.ir.Typ) ¶ WebFeb 26, 2013 · HHS Headquarters.
