background emissionの例文

• The seeker head improvements were only minor changes to allow better discrimination of the target signal against background emissions.
• Since Idria has natural mercury reservoirs, it is important to factor in these background emissions in measuring the total impact from mining itself.
• Two photon imaging allows imaging of living tissues up to a very high depth by enabling greater excitation light penetration and reduced background emission signal.
• He was best known for his work measuring the Cosmic Microwave Background emission, providing upper limits on the CMB anisotropies, which began with observations on cold winter nights at Jodrell Bank Observatory in the late 1970s, before relocating his telescopes up the mountain on Tenerife in the early 1980s to take advantage of the clearer atmosphere at that location.
• Taking advantage of the fact that the clear sky gives strong and constant background emission at below 2 micrometer range, peaking at visual light ( 0.4 to 0.7 micrometer ) wavelengths at which PbS in 295 kelvins temperature still provides a response, the seeker head is used to track a change of radiation from the target compared to the background.
