The measurements were done in reflection mode using the reduced reflectance technique in ambient conditions.
Tablets were scanned in reflection mode on a benchtop NIRS.
Both scanners are used in reflection mode taking into account landscape and portrait scanning positions.
Further measurements were performed with a variable-angle spectroscopic ellipsometry M-2000UII, J.A. Woollam Co., Inc.) in reflection mode at four angles (55°, 60°, 65° and 70°).
This intrinsic sensor works in reflection mode, and the transduction takes place in the light that travels through the core of the fibre.
The samples were then imaged in between two perpendicular light polarizers using a Leica DM750 P instrument in reflection mode with a ×4 magnification using Leica Application Suite V4.2 software.
The differences between measurements made in transmission mode and in reflection mode are summarized, and the corresponding equations for data analysis are introduced.
However this does not affect the absorption spectra properties in the red region of analysis which is the main area for use using desktop scanners in reflection mode.
Plaque biofilms formed in vivo on human enamel were subjected to a number of different chemical conditions while under observation by confocal laser scanning microscopy in reflection mode.
Using a transverse wave probe in reflection mode, phase and amplitude of its output signal are measured as a function of the polarization angle.
The implementation is in the form of a time delay spectrometry (TDS) system operating in reflection mode whose advantages are improved signal-to-noise ratio even with low peak power relative to conventional pulse-echo methods.
