reflectometer
reflecˈtometer [See -ometer.] Any of various instruments for measuring quantities associated with reflection; spec. (a) one for measuring the critical angle of a transparent solid so that its refractive index may be calculated; (b) one for measuring the intensity of light reflected or scattered by a...

Optical time-domain reflectometer
An optical time-domain reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber. It is the optical equivalent of an electronic time domain reflectometer which measures the impedance of the cable or transmission line under test. wikipedia.org

Signal reflection
Because damage to the cable can cause reflections, an instrument called an electrical time-domain reflectometer (ETDR; for electrical cables) or an optical time-domain reflectometer (OTDR; for optical cables) can be used to locate the damaged part of a cable. wikipedia.org

Rigorous coupled-wave analysis
Studies have shown that the limited wavelength range of a standard reflectometer (375 - 750 nm) does not provide the sensitivity to accurately measure However, by using a reflectometer with the wavelength range extended from 190 - 1000 nm, it is possible to accurately measure these smaller structures. wikipedia.org
