33. Improved Near-Infrared Spectral Responsivity Scale
Series: Journal of Research (NIST JRES)
Published: 9/1/2000
Authors: Ping-Shine Shaw, Thomas C Larason, R Gupta, Steven W Brown, Keith R Lykke
Abstract: A cryogenic radiometer-based system was constructed at the National Institute of Standards and Technology (NIST) for absolute radiometric measurements to improve detector spectral responsivity scales in the wavelength range from 900 nm to 1800 nm. I ...
