22. Characterization of Hyperspectral Imaging and Analysis via Microarray Printing of Dyes
Published: 2/22/2011
Authors: Matthew Lawrence Clarke, Maritoni Abatayo Litorja, David W Allen, Daniel Victor Samarov, Jeeseong Hwang
Abstract: The application of hyperspectral imaging requires rigorous characterization of the spatial and spectral imaging domains of the system. We present a microarray printing methodology for the testing of absorption or reflectance microscopy measurements. ...

23. An examination of spectral diversity of medical scenes for hyperspectral projection
Published: 2/14/2011
Author: David W Allen
Abstract: There are numerous medical conditions which may benefit from hyperspectral imaging. The imagers used for these conditions will need to have the performance validated to ensure consistency, gain acceptance and clear regulatory hurdles. NIST has been ...

24. Hyperspectral image projection of a pig kidney for the evaluation of imagers used for oximetry
Published: 2/10/2011
Author: David W Allen
Abstract: Hyperspectral image projection applied to optical medical imaging can provide a means to evaluate imager performance. This allows repeated viewing of unique surgical scenes without the need for costly experiments on patients. Additionally, the genera ...

26. Hyperspectral Image Compressive Projection Algorithm
Published: 6/1/2009
Authors: Joseph Paul Rice, Jorge Enrique Neira, David W Allen
Abstract: We describe a compressive projection algorithm and quantitatively assess its performance when used with a Hyperspectral Image Projector (HIP). The HIP is being developed by NIST for system-level performance testing of hyperspectral and multispectral ...

27. Hyperspectral Projection of a Coral Reef Scene using the NIST Hyperspectral Image Projector
Published: 6/1/2009
Authors: David W Allen, Joseph Paul Rice, James A Goodman
Abstract: Improving the understanding of the optical scene components associated with coral reef imagery will advance the ability to map and monitor coral reefs using remote sensing. One tool that may aid in understanding the components in these scenes is the ...

28. Holmium Oxide Glass Wavelengths Standards
Series: Journal of Research (NIST JRES)
Published: 1/1/2008
Author: David W Allen
Abstract: Holmium oxide glass has been used as a wavelength standard for over four decades. These standards have shown very little variation from batch to batch and from one manufacturer to another. NIST has certified and recertified holmium oxide glass samp ...

30. Evaluation of a Portable Hyperspectral Imager for Medical Imaging Applications
Published: 10/2/2007
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 ...
