Detection at range
WebJun 1, 2024 · Detecting mid-infrared light, one photon at a time. For some 30 years, scientists have used superconducting materials to record the tiniest specks of light imaginable — individual photons, or single particles of light. However, these detectors, which consist of ultracold wires only about one-thousandth the diameter of a human hair, were ... WebBackground. The measurement of scattered light from an illuminated sample forms the basis of the so-called classical light scattering measurement. Historically, such measurements were made using a single detector rotated in an arc about the illuminated sample. The first commercial instrument (formally called a "scattered photometer") was the Brice-Phoenix …
