Journal ArticleDOI
Supercontinuum sources for metrology
John T. Woodward,Allan W. Smith,Colleen A Jenkins,Chungsan Lin,Steven W. Brown,Keith R. Lykke +5 more
TL;DR: Supercontinuum (SC) sources are novel laser-based sources that generate a broad, white-light continuum in single-mode photonic crystal fibres as mentioned in this paper, which can be used for fundamental optical metrological applications.
Journal ArticleDOI
Precise Measurement of Lunar Spectral Irradiance at Visible Wavelengths
TL;DR: A measurement of lunar spectral irradiance with an uncertainty below 1 % from 420 nm to 1000 nm is reported, suggesting that lunar observations are a possible solution for aerosol monitoring during the polar winter and can provide nighttime measurements to complement aerosol data collected with sun photometers.
Journal ArticleDOI

Smith,Ian Sullivan,Kohji Tsumura,Takehiko Wada,Michael Zemcov,Michael Zemcov +29 more
TL;DR: In this article, a near-infrared spectrometer was designed to measure the absolute intensity of the solar 854.2 nm Ca II Fraunhofer line, scattered by interplanetary dust, in the zodiacal light (ZL) spectrum.
Journal ArticleDOI
RAVAN: CubeSat Demonstration for Multi-Point Earth Radiation Budget Measurements
William H. Swartz,Steven R. Lorentz,Stergios J. Papadakis,Philip M. Huang,Allan W. Smith,David M. Deglau,Yinan Yu,Sonia M. Reilly,Nolan M. Reilly,Donald E. Anderson +9 more
TL;DR: The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) 3U CubeSat mission is a pathfinder to demonstrate technologies for the measurement of Earth’s radiation budget, the quantification of which is critical for predicting the future course of climate change.
Journal ArticleDOI
Low-background temperature calibration of infrared blackbodies
TL;DR: In this paper, the performance of the absolute cryogenic radiometers (ACRs) used as detector standards in the calibration of low-background blackbodies is compared with a trap detector calibrated against the NIST primary optical power measurement standard.
