24. A Simple Stray-light Correction Method for Array Spectroradiometers
Published: Date unknown
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 ...

25. Characterization and Correction of Stray Light in Optical Instruments
Published: Date unknown
Authors: Yuqin Zong, Steven W Brown, G Meister, R Barnes, Keith R Lykke
Abstract: Improperly imaged, or scattered, optical radiation within an instrument is difficult to properly characterize and is often the dominant residual source of measurement error. Scattered light can originate from the spectral components of a point sour ...

26. Correction of Stray Light In Spectroradiometers and Imaging Instruments
Published: Date unknown
Authors: Yuqin Zong, Steven W Brown, Keith R Lykke, Yoshihiro Ohno
Abstract: Measurement errors from stray light, spectral or spatial, are inevitable and are often the dominant source of error in spectroradiometers and imaging radiometers/photometers. We have developed a simple matrix method for correcting spatial stray light ...

27. Correction of Stray Light in Spectrographs: Implications for Remote Sensing
Published: Date unknown
Authors: Yuqin Zong, Steven W Brown, Bettye C Johnson, Keith R Lykke, Yoshihiro Ohno
Abstract: Spectrographs are used in a variety of applications in the field of remote sensing for radiometric measurements due to the benefits of measurement speed, sensitivity, and portability. However, spectrographs are single grating instruments that are su ...

28. Detector-Based Integrating Sphere Photometry
Published: Date unknown
Authors: Yoshihiro Ohno, Yuqin Zong
Abstract: A new luminous flux calibration facility using a 2.5 m integrating sphere has been developed at NIST. The Absolute Integrating-Sphere Method, developed for realization of the lumen in 1995, has been applied to routine calibration measurements of lum ...

29. Evaluation of a Portable Hyperspectral Imager for Medical Imaging Applications
Published: Date unknown
Authors: David W Allen, Maritoni Abatayo Litorja, Steven W Brown, Joseph Paul Rice, Yuqin Zong
Abstract: Portable hyperspectral imagers are becoming commonly available as a commercial product. A liquid crystal tunable filter based CCD imager was evaluated and characterized for spectral stray light using a tunable laser facility. The hyperspectral imag ...
