WebJun 19, 2024 · Rayleigh optical time-domain reflectometers (OTDRs) with spectrally broad emitting sources are routinely used to measure losses in optical communication lines and detect fiber defects over distances of many tens of kilometers and a spatial resolution of 1–100 m, generally determined by the probing pulse duration. Webm is the relative optical air mass; m0 the optical air mass at sea level. Rayleigh (m) is the integrated Rayleigh optical thickness, due to pure molecular scattering.

WebJun 1, 2009 · Rayleigh discussed the similar situation of a bright line; if a line is bright enough, it will be visible no matter how narrow. However, its width will be illusionary, depending on the resolution of the optical device. Notably, Rayleigh correctly stated that it may vary with the character of the detail of the object (e.g., points, lines, planes). WebJun 1, 2024 · To this end, we investigate the Rayleigh-Wood anomalies arising from a plasmonic gold thin film nanohole array on glass through theoretical calculations and FDTD simulations. Theoretical investigation of Rayleigh-Wood anomaly provides an approximation of optical transmission features independent of hole geometrical shape. healthiest alkaline water
