1. NIST traceable measurements of radiance and luminance levels of night-vision-goggle test-instruments
Published: 5/7/2014
Authors: George P Eppeldauer, Vyacheslav B Podobedov
Abstract: In order to perform radiance and luminance level measurements of night-vision-goggle (NVG) test instruments, NIST developed new-generation transfer-standard radiometers (TR). The new TRs can perform low-level radiance and luminance measurements with ...

2. Development of in-situ calibration method for current-to-voltage converters for high-accuracy SI-traceable low-DC-current measurements
Published: 9/20/2013
Authors: George P Eppeldauer, Howard W Yoon, Dean G Jarrett, Thomas C Larason
Abstract: For photocurrent measurements with low uncertainties, wide-dynamic range reference current-to-voltage converters and a new converter calibration method have been developed at the National Institute of Standards and Technology (NIST). The high feedba ...

3. Evaluation of dome-input geometry for pyroelectric detectors
Published: 6/24/2013
Authors: Jinan Zeng, Leonard M Hanssen, George P Eppeldauer
Abstract: Dome-input pyroelectric radiometers with different black coatings were developed to extend the spectral responsivity scale from near infrared (NIR) to 20 μm. The reflective dome with shiny gold-coating has been known to be an efficient light t ...

4. Spectral responsivity based calibration of photometer and colorimeter standards
Published: 6/19/2013
Author: George P Eppeldauer
Abstract: Several new generation transfer- and working-standard illuminance meters and tristimulus colorimeters have been developed at the National Institute of Standards and Technology (NIST) to measure all kinds of light sources with low uncertainty. The spe ...

5. Standardization of Broadband UV Measurements
Published: 1/1/2013
Author: George P Eppeldauer
Abstract: The CIE standardized rectangular-shape UV response functions can be realized only with large spectral mismatch errors. The spectral power-distribution of UV sources is not standardized. Accordingly, the readings of different types of UV meters, even ...

6. Spectral responsivity calibrations of two type pyroelectric radiometers using three different methods
Published: 8/15/2012
Authors: Jinan Zeng, George P Eppeldauer, Leonard M Hanssen, Vyacheslav B Podobedov
Abstract: Spectral responsivity calibrations of two different type pyroelectric radiometers have been made in infrared region up to 14 μm in power mode using three different calibration facilities at NIST. One pyroelectric radiometer is a temperature-cont ...

7. PV-MCT working standard radiometer
Published: 4/24/2012
Authors: George P Eppeldauer, Vyacheslav B Podobedov
Abstract: Sensitive infrared working-standard detectors with large active area are needed to extend the signal dynamic range of the National Institute of Standards and Technology (NIST) pyroelectric transfer-standards used for infrared spectral power responsiv ...

8. Infrared detector calibrations
Published: 3/22/2012
Authors: George P Eppeldauer, Vyacheslav B Podobedov
Abstract: An InSb working standard radiometer, first calibrated at NIST in 1999 against a cryogenic bolometer, was recently calibrated against a newly developed low-NEP pyroelectric transfer standard detector. The pyroelectric transfer standard, which can oper ...

9. Extension of the NIST spectral power-responsivity calibration service to 2500 nm
Published: 3/2/2012
Authors: George P Eppeldauer, Howard W Yoon, Jinan Zeng, Thomas C Larason, Jeanne M Houston, Vladimir Khromchenko
Abstract: The National Institute of Standards and Technology (NIST) is working to extend the upper wavelength limit of the spectral power-responsivity calibration service from 1800 nm to 2500 nm. This extension is based on extended-InGaAs (EIGA) transfer- and ...

10. New method for spectral irradiance and radiance responsivity calibrations using kHz pulsed tunable optical parametric oscillators
Published: 3/2/2012
Authors: Yuqin Zong, Steven W Brown, George P Eppeldauer, Keith R Lykke, Yoshihiro Ohno
Abstract: Continuous-wave (CW) tunable lasers have been used for detector calibrations, especially for spectral irradiance and radiance responsivity, for many years at the National Institute of Standards and Technology (NIST) and other national metrology insti ...
