Simulation of FTIR reflection spectra in non normal incidence

Reflection contributions to the dispersion artefact in FTIR spectra of single biological cells.

Fourier transform infrared spectra of a single cell in transflection geometry are seen to vary significantly with position on the cell, showing a distorted derivative-like lineshape in the region of the optically dense nucleus. A similar behaviour is observable in a model system of the protein albumin doped in a potassium bromide disk. It is demonstrated that the spectrum at any point is a weig...

Stationary property of normal-incidence reflection from isotropic surfaces

Influence of Bottom Trawling on the Normal- Incidence Reflection Coefficient

A North Sea area characterized by muddy, sandy, and gravelly sediments is surveyed with a single-beam echo sounder operating at 12, 38, and 200 kHz. Closely spaced survey legs and a high repetition rate of five sounder pings per second allow the production of echo energy maps with a high spatial resolution. These energy maps reveal a series of string-like features, which are believed to be due ...

Narrow band resonant grating of 100% reflection under normal incidence.

A resonant grating mirror comprising a multilayer submirror and a grating slab waveguide submirror exhibiting constructive mutual reflection is shown experimentally to provide zero transmission. Its reflection line width of less than 1 nm, its polarization selectivity and low overall loss make the device usable as a longitudinal mode filter in a disk laser in the 1000-1100 nm wavelength range.

Characterization of Pigment-binding Media Systems - Comparison of Non-invasive In-situ Reflection Ftir with Transmission Ftir Microscopy

destructive analyses in the region from 4000-450 cm-1 with a measuring point diameter of approximately 5 mm, was tested for the identification of pigments and binding media in two modern paintings and several mockups with traditional pigment-binding media combinations. Comparative measurements were carried out with minute samples using a diamond cell for transmission FTIR microscopy. The result...
