laser induced fluorescence

Laser-Induced Fluorescence (LIF) Fluorescent dyes (molecules) can absorb light at one frequency and subsequently re-emit (fluoresce) light at a different frequency. In experiments, the dyes are excited by laser light whose frequency closely matches the excitation frequency of

Laser induced fluorescence (LIF) is a very sensitive technique for the species-selective spatially resolved detection of ground state atoms, which are the most populated state in a low

Two-color Planar Laser Induced Fluorescence (LIF) was used to experimentally capture the temperature profile above a horizontally oriented copper surface using PF-5060 as the dielectric working fluid.

Laser-induced fluorescence detection is the most frequently applied detection technique on lab-on-a-chip devices. As most (bio)molecules of interest are not fluorescent, labeling is required

The High-Tech Group makes full use of its global network in the field of advanced technologies to offer top of the line electronic device systems, scientific and medical systems, and industrial and IT systems to become the world's number one

Planar Laser-Induced Fluorescence, or PLIF, is an optical measurement technique based upon fluorescence emitted from chemical species excited by planar laser light. Essentially a sheet of laser light is passed through a flow field, and the subsequent fluorescence relaxation event is captured on a digital camera.

30/05/  · Laser-induced fluorescence (LIF) is an interesting combination of absorption and emission spectroscopy. It is naturally more complicated than either of these methods alone, both experimentally and theoretically. In return, it offers higher sensitivity compared to single-pass absorption measurements, good spatial resolution given by intersection

Instrument composition: Like ordinary fluorescence detectors, laser-induced fluorescence detectors are mainly composed of light sources, optical systems, detection cells, and light detection elements. The most important difference between the two is that the light source of laser-induced fluorescence detectors is a laser.

The research presented here aims at providing a deeper understanding of the formation of nitric oxide in diesel combustion. To this end, in-cylinder distributions of nitric oxide (NO) were acquired by laser-induced fluorescence (LIF) in a rapid compression machine at conditions representative of a modern diesel passenger vehicle.

Fluorescence light microscopy is one of the most frequently used imaging techniques in biological research. However, despite extensive efforts over the past two centuries, the details of the structural organization and interaction of complex molecular assemblies have remained largely concealed. For PA-GFP, readout-laser-induced activation

Laser induced fluorescence (LIF) is a very sensitive technique for the species-selective spatially resolved detection of ground state atoms, which are the most populated state in a low temperature plasma. LIF uses a single photon per excitation of the probed atom or molecule.

In a Laser Induced Fluorescence (LIF) approach a laser is employed as the excitation source. The laser provides a more spectrally intense and selective excitation with a more defined and narrower spectral background level. The laser spectroscopy capability can be tailored with the application to provide enhanced accuracy and repeatability in

Laser Induced Fluorescence (LIF) LIF imaging is a molecule specific visualization method with high spatial and temporal resolution. If the fluid itself contains no LIF-active species (like N2, CH4 or water), flow seeding with fluorescent markers (tracers) is used for scalar flow field imaging (Tracer-LIF).
