For one test, a device called a reflectometer is used to measure the degree of whiteness in processed tuber samples destined to become chips.
The reflectometer has demonstrated wavelength resolution of about 1000 with out-of-band radiation levels of less than 0.2%.
They also left behind scientific apparatus, including a seismograph to measure Moon quakes, and a laser reflectometer which allowed incredibly accurate measurements of the distance between the Earth and the Moon.
The Northern Sand Plain scientists also found a way to irrigate crops more precisely by a weekly check of soil moisture with a portable time domain reflectometry unit.
We have shown that phase-sensitive specular neutron reflectometry can be used to determine accurately and unambiguously the SLD depth profiles of biomimetic membranes with a resolution in the subnanometer range.
