21. Using the Substitution Method with a Monitor Detector will Improve the Accuracy of Absolute Spectral Power Responsivity Measurements
Published: 11/1/2001
Authors: Sally Skidmore Bruce, Thomas C Larason
Abstract: Many radiometric, photometric, and colorimetric applications require the determination of the absolute spectral power responsivity of photodetectors. The absolute spectral power responsivity is the ratio of the photodetector's output (in amperes ...

22. The New Ultraviolet Spectral Responsivity Scale Based on Cryogenic Radiometry at Synchrotron Ultraviolet Radiation Facility III
Published: 5/1/2001
Authors: Ping-Shine Shaw, Thomas C Larason, R Gupta, Steven W Brown, Robert Edward Vest, Keith R Lykke
Abstract: The recently completed upgrade of the Synchrotron Ultraviolet Radiation Facility (SURF III) at the National Institute of Standards and Technology (NIST) has improved the accuracy of radiometric measurements over a broad spectral range from the infrar ...

23. Responsivity calibration methods for 365 nm irradiance meters
Published: 4/1/2001
Authors: Thomas C Larason, Steven W Brown, George P Eppeldauer, Keith R Lykke

24. Absolute Radiometric Calibration of Digital Imaging Systems, ed. by M.M. Blouke, J. Canosa, N. Sampat
Published: 1/1/2001
Authors: Steven W Brown, Thomas C Larason, C Habauzit, George P Eppeldauer, Yoshihiro Ohno, Keith R Lykke

25. Avoiding Errors in UV Radiation Measurements
Published: 1/1/2001
Author: Thomas C Larason

26. Method of Measuring Shunt Resistance of Photodiodes
Published: 1/1/2001
Authors: P R Thompson, Thomas C Larason
Abstract: A method of measuring the shunt resistance of diodes, specifically photodiodes, is examined and the procedure of how the method is implemented using LabVIEW is detailed. Rudimentary comparison with other accepted methods in industry is done. The un ...

27. Sources of Error in UV Radiation Measurements
Published: 1/1/2001
Authors: Thomas C Larason, C L Cromer

28. Sources of Uncertainty in UV Radiation Measurements
Published: 1/1/2001
Authors: Thomas C Larason, Christopher L Cromer
Abstract: Increasing commercial, scientific, and technical applications involving ultraviolet (UV) radiation has led to the demand for improved understanding of the performance of instrumentaion used to measure this radiation. There has been an effort by manu ...

29. 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 ...

30. Realization of a spectral radiance responsivity scale with a laser-based source and Si radiance meters
Published: 1/1/1999
Authors: George P Eppeldauer, Steven W Brown, Thomas C Larason, M Racz, R Lykke k
