1. Stray light correction algorithm for multi-spectral hyperspectral spectrographs
Published: 6/1/2012
Authors: Michael Feinholz, Stephanie J Flora, Steven W Brown, Yuqin Zong, Keith R Lykke, Mark A. Yarbrough, Bettye C Johnson, D. K. Clark
Abstract: An algorithm is developed to correct a multi-channel fiber-coupled spectrograph for stray or scattered light within the system. The efficacy of the algorithm is evaluated based on a series of validation measurements of sources with different spectra ...

2. Radiometer standard for absolute responsivity calibrations from 950 nm to 1650 nm with 0.05% (k = 2) uncertainty
Published: 6/2/2009
Authors: George P Eppeldauer, Howard W Yoon, Yuqin Zong, Thomas C Larason, Allan W. Smith, M. Racz
Abstract: A sphere-input transfer-standard detector has been developed to calibrate detectors and radiometers for absolute spectral power, irradiance, and radiance responsivity in the near-IR range with uncertainties similar to those of silicon trap-detector c ...

3. NIST SPECTRALLY TUNABLE LIGHTING FACILITY FOR COLOR RENDERING AND LIGHTING EXPERIMENTS
Published: 5/29/2009
Authors: Carl C Miller, Yoshihiro Ohno, Wendy L Davis, Yuqin Zong, Kevin Dowling
Abstract: The National Institute of Standards and Technology has developed a spectrally tunable lighting facility to allow state-of-the-art vision experiments on color rendering and lighting. The facility is composed of two cubicles, each lit by a spectrally ...

4. PRACTICAL METHOD FOR MEASUREMENT OF AC-DRIVEN HIGH-POWER LEDS
Published: 7/14/2008
Authors: Yuqin Zong, Yoshihiro Ohno, Pei-ting Chou
Abstract: Alternating-current (AC) driven high-power LEDs are available and used in SSL products. AC LEDs operate directly from a mains supply and thus have advantages in simplifying product design, increasing product reliability, and extending product lifetim ...

5. NEW PRACTICAL METHOD FOR MEASUREMENT OF HIGH-POWER LEDS
Published: 7/11/2008
Authors: Yuqin Zong, Yoshihiro Ohno
Abstract: The measurement of high-power light emitting diodes (LEDs) has been difficult because they are highly sensitive to thermal operating conditions, and there has been a lack of common methods that can be used by both LED manufactures and users to acquir ...

6. Realization of total spectral radiant flux scale and calibration service at NIST
Published: 1/1/2007
Authors: Yuqin Zong, Yoshihiro Ohno

7. A Simple Stray-light Correction Method for Array Spectroradiometers
Published: 2/20/2006
Authors: Yuqin Zong, Steven W Brown, Bettye C Johnson, Keith R Lykke, Yoshihiro Ohno
Abstract: In many applications, the measurement accuracy of spectroradiometers, particularly instruments with a single dispersive element, is limited by the presence of stray radiation within the instrument. A simple, practical method has been developed to co ...
