Laser induced fluorescence spectroscopy in the ultraviolet regime has been used for the detection of biochemical through a fiber coupled CCD detector from a distance of 2 m. The effect of concentration and laser excitation energy on the fluorescence spectra of nicotinamide adenine dinucleotide (NADH

29/08/  · The laser-induced fluorescence is based on the fluorophore excitation by electromagnetic radiation. Generally, the radiation used to induce the fluorescence is near-UV

Laser Induced Fluorescence (LIF) is an optical spectroscopic technique where a sample is excited with a laser, and the fluorescence emitted by the sample is subsequently captured by a photodetector. LIF can be understood as a class of fluorescence spectroscopy where the usual lamp excitation is replaced by a laser source.

X(1,0) transition using a quasi-linear laser-induced fluorescence scheme. The peak number density is (1.0 ± 0.4)x10 13 cm -3 or 2.4 ± 1 ppm at 1900 K, with a flame front width of 250 µm

A pulsed, tunable dye laser is used to obtain either the excitation spectrum for the A 2Πi-X 2Σ+ (0,0) band of CO+, or the time resolved fluorescence from individual rotational levels of the upper state for this transition. The ions are formed by reacting CO with helium metastable atoms produced in a dc discharge. Although the rotational structure of the A 2Πi (v = 0) state is well known

Laser induced fluorescence experiment Posted on 29.10. (01.07. ) by George Fomitchev In the experiment, we are using 3 types of lasers: red 650 nm, green 532 nm, blue 450 nm. Here we used various concentrations of chlorophyll and fluorescein and olive oil as fluorescence liquids.

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.

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.

Planar-Laser-Induced Fluorescence (PLIF) is an optical diagnostic that can probe a single chemical species, such as the hydroxyl radical or the methylidine radical, in a chemically reacting flow field, providing information about the concentration, temperature, location, lifespan, and distribution of that species in the test region.
