Quantitative phase spectroscopy
Quantitative phase spectroscopy is presented as a novel method of measuring the wavelength-dependent refractive index of microscopic volumes. Light from a broadband source is filtered to an ~5 nm bandwidth and rapidly tuned across the visible spectrum in 1 nm increments by an acousto-optic tunable filter (AOTF). Quantitative phase images of semitransparent samples are recovered at each waveleng...
متن کاملGas-phase databases for quantitative infrared spectroscopy.
The National Institute of Standards and Technology (NIST) and the Pacific Northwest National Laboratory (PNNL) are each creating quantitative databases containing the vapor-phase infrared spectra of pure chemicals. The digital databases have been created with both laboratory and remote-sensing applications in mind. A spectral resolution of approximate, equals 0.1 cm(-1) was selected to avoid de...
متن کاملQuantitative Spectroscopy of Photospheric-Phase Type II Supernovae
We present first results on the quantitative spectroscopic analysis of the photospheric-phase of Type II supernovae (SN). The analyses are based on the model atmosphere code, CMFGEN, of Hillier & Miller (1998) which solves the radiative transfer and statistical equilibrium equations in expanding outflows under the constraint of radiative equilibrium. A key asset of CMFGEN is its thorough treatm...
متن کاملQuantitative phase imaging and Raman micro-spectroscopy applied to Malaria
Background Malaria is due to parasitism of red blood cells (RBC) by protozoan parasites of the genus Plasmodium. Three main parameters have to be determined for patient treatment: parasite species, the rate of infected blood cells (parasitemia), and development stage. Even if a series of laboratory techniques are available, a suited treatment needs microscopy skills [1]. Microscopic observation...
متن کاملQuantitative enantioselective Raman spectroscopy.
Analytical methods for quantitative enantioselective measurements are highly desirable in the life sciences. Existing technologies have disadvantages such as limited temporal resolution, the need for molecular labeling, or high experimental complexity. To overcome these limitations, this work presents a method based on conventional Raman spectroscopy. A systematic investigation of the key param...
