peer agreement (net): +1
peer agreement (net): +1light attenuation per meter Explanation: it seems that this is a measure of how the sensitivity of the alarm reduces as a function of the distance. |

21 hrs confidence: peer agreement (net): +1
peer agreement (net): +1per meter obscuration Explanation: Seems to be the normal way of expressing this. Similar to optical density but for high sensitivity detectors. https://gesconv.com/shop/ultra-high-sensitivity-laser-smoke-detector/ https://www.notifierfiresystems.co.uk/docs/notifierfiresystems/en/s/NOTIFIER_Addressable_VIEW_Laser_High_Sensitivity_Smoke_Detector_Specific |

attenuation of light per meter Explanation: Kenne ich auch als Lichtschwächung. Substantive attenuation of light - of a film base [TECH.] die Lichtschwächung Pl.: die Lichtschwächungen https://dict.leo.org/englisch-deutsch/Lichtschwächung#sectio... Lichtdämpfung zwischen 700...1700 nm durch fundamentale Materialeigenschaften und Verunreinigungen. https://de.m.wikipedia.org/wiki/Lichtwellenleiter Attenuation in fiber optics, also known as transmission loss, is the reduction in intensity of the light beam (or signal) as it travels through the transmission medium. Attenuation in fiber optics, also known as transmission loss, is the reduction in intensity of the light beam (or signal) as it travels through the transmission medium. -------------------------------------------------- Note added at 2 days 3 hrs (2019-03-23 14:01:08 GMT) -------------------------------------------------- In physics, attenuation or, in some contexts, extinction is the gradual loss of flux intensity through a medium. For instance, dark glassesattenuate sunlight, lead attenuates X-rays, and water and air attenuate both light and soundat variable attenuation rates. https://en.m.wikipedia.org/wiki/Attenuation -------------------------------------------------- Note added at 2 days 8 hrs (2019-03-23 18:14:48 GMT) -------------------------------------------------- Other expressions: The transparency of aquatic systems is represented by a value referred to as the extinction coefficient or diffuse attenuation coefficient (Kd or η in older literature). : The Rayleigh scattering extinction coefficient for particle-free air is 0.012 km−1 for “green” light (γ = 0.05 μm) at sea level.29 This permits a visual range of ∼320 km. : Suspended particles are the most important factor in visibility reduction. In most instances, the visual quality of air is controlled by particle scattering and is characterized by the extinction coefficientbscat. The size of particles plays a crucial role in their interaction with light. Other factors are the refractive index and shape of the particles, although their effect is harder to measure and is less well understood. https://www.sciencedirect.com/topics/earth-and-planetary-sci... |

extinction coefficient [1/m] Explanation: Further research revealed a still better and more scientific term, which deserves a separate answer: extinction coefficient. The transparency of aquatic systems is represented by a value referred to as the extinction coefficient or diffuse attenuation coefficient (Kd or η in older literature). : The Rayleigh scattering extinction coefficient for particle-free air is 0.012 km−1 for “green” light (γ = 0.05 μm) at sea level.29 This permits a visual range of ∼320 km. : Suspended particles are the most important factor in visibility reduction. In most instances, the visual quality of air is controlled by particle scattering and is characterized by the extinction coefficient bscat. The size of particles plays a crucial role in their interaction with light. Other factors are the refractive index and shape of the particles, although their effect is harder to measure and is less well understood. https://www.sciencedirect.com/topics/earth-and-planetary-sci... The coefficient k in this equation is known as the extinction coefficient. In the example we have just presented, k=0.035 per meter https://books.google.de/books?id=lE4HUmEZzhIC&pg=PA92&lpg=PA... |
