"The small size and lightweight high-frequency
reflectometers in the broadband configurations enhance maneuverability and probe positioning in applications such as on-wafer measurements and near-field scanning of antennas and circuits.

reflectometer systems investigation", Ph.D.
These studies have demonstrated that input acoustic impedance measurements (which provide valuable information on the wind instrument under evaluation) made by using acoustic reflectometry are quite close to theory and easily applied; likewise, having some restrictions in the information obtained at high frequencies and in the size of the
reflectometer, which is of considerable length [1].
A commercially available Fourier transform infrared spectroscopy (FTIR)
reflectometer (SOC 400T) was used in this study.
In his fundamental book of 1874 "neue Apparate zur Bestimmung des Brechungs- und Zerstreuungsvermbgens fester und flussiger Korper" (New Devices for the Determination of the Refractive and Dispersive Capabilities of Solid and Fluid Bodies), Ernst Abbe presented design drawings of a total
reflectometer (see Fig.
Reflectometers measure the intensity of reflected light, usually at normal (90[degrees]) incidence to the sample.
The experiment was carried out at the PNPI
reflectometer of the WWR-M reactor.
The OptiVisor 400 Optical Time Domain
Reflectometer provides full OTDR testing in a rugged, portable unit.
We conducted a study of 80 patients to evaluate the accuracy of a commercially available acoustic
reflectometer in identifying the presence or absence of otitis media with effusion (OME).
MEGGER'S new XC8513 dual-wavelength crosschecking
reflectometer has the ability to test at 850nm and 1300nm.
THE TIME DOMAIN
reflectometer (TDR) is the de facto standard for characterizing the impedance profile and transmission properties of a fabricated circuit board trace.
E 2302, Standard Test Method for Measurement of Luminance Coefficient Under Diffuse Illumination of Pavement Marking Materials with CEN-Prescribed Geometry Using a Portable
Reflectometer, is used to evaluate horizontal road stripes, symbols, and pavement surfaces.
