1. Spectral reflectance variability of skin and attributing factors
Published: 5/21/2015
Authors: Catherine C Cooksey, Benjamin K Tsai, David W Allen
Abstract: Knowledge of the spectral reflectance signature of human skin over a wide spectral range will help advance the development of sensing systems for many applications, ranging from medical treatment to security technology. A critical component of the s ...

2. Numerical, benchtop, and in vivo phantoms for hyperspectral imaging of ischemic wounds
Published: 5/14/2015
Authors: David W Allen, Jeeseong Hwang, Maritoni Abatayo Litorja, Joseph Paul Rice
Abstract: Biomedical optical imaging has the potential to achieve high spatial resolution and high functional sensitivity for non-invasive assessment of ischemic wounds. However, clinical acceptance of many optical imaging devices is hampered by poor repro ...

3. Bidirectional reflectance scale comparison between NIST and PTB
Published: 5/1/2015
Authors: Catherine C Cooksey, Maria E Nadal, David W Allen, Kai-Olaf Hauer, Andreas Hoepe
Abstract: A comparison of bidirectional reflectance scales between the National Institute of Standards and Technology (NIST) and the Physikalisch-Technische Bundesanstalt (PTB) has been performed. Measurements of two sets of white diffuse reflectance standard ...

4. Establishment and application of the 0/45 reflectance factor scale over the shortwave infrared
Published: 4/1/2015
Authors: Catherine C Cooksey, David W Allen, Benjamin K Tsai, Howard W Yoon
Abstract: This paper describes the establishment and application of the 0/45 reflectance factor scale in the shortwave infrared (SWIR) from 1100 nm to 2500 nm. Design, characterization, and the demonstration of a 4-stage, extended indium-gallium-arsenide radi ...

5. Making digital phantoms with spectral and spatial light modulators for quantitative applications of hyperspectral optical medical imaging devices
Published: 3/6/2015
Authors: Bonghwan B. Chon, fuyuki Tokumasu, Ji Youn Lee, David W Allen, Joseph Paul Rice, Jeeseong Hwang
Abstract: We present a procedure to generate digital phantoms with a hyperspectral image projector (HIP) consisting of two liquid crystal on silicon (LCoS) spatial light modulators (SLMs). The digital phantoms are 3D image data cubes of the spatial distri ...

6. Measurement of the optical properties of solid biomedical phantoms at the National Institute of Standards and Technology
Published: 3/6/2015
Authors: Paul Lemaillet, David W Allen, Jeeseong Hwang
Abstract: Solid phantoms that serve as a proxy for human tissue and provide a convenient test subject for optical medical imaging devices. In order to determine quantitative performance of a given system, the absolute optical properties of the subject mus ...

7. An analysis of the nonlinear spectral mixing of didymium and soda-lime glass beads using hyperspectral imagery (HSI) microscopy
Published: 6/13/2014
Authors: Ronald Resmini, Robert S Rand, Christopher Deloye, David W Allen
Abstract: Nonlinear spectral mixing occurs when materials are intimately mixed. Intimate mixing is a common characteristic of granular materials such as soils. A linear spectral unmixing inversion applied to a nonlinear mixture will yield subpixel abundance es ...

8. A collection and statistical analysis of skin reflectance signatures for inherent variability over the 250 nm to 2500 nm spectral range
Published: 6/4/2014
Authors: Catherine C Cooksey, Benjamin K Tsai, David W Allen
Abstract: The spectral reflectance signature of human skin provides opportunities to advance observations ranging from medical treatment to security applications. In this study 28 volunteers participated in a skin reflectance measurement of the inside of the r ...

9. Reflectance measurements of human skin from the ultraviolet to the shortwave infrared (250 nm to 2500 nm)
Published: 5/29/2013
Authors: Catherine C Cooksey, David W Allen
Abstract: While published literature of the optical properties of human skin is prevalent for the visible region, data are sparse in the ultra violet and shortwave infrared. Spectral imaging has expanded from primarily an earth remote sensing tool to a range ...

10. A microscene approach to the evaluation of hyperspectral system level performance
Published: 5/18/2013
Authors: David W Allen, Ronald Resmini, Christopher Deloye
Abstract: Assessing the ability of a hyperspectral imaging (HSI) system to detect the presence of a substance or to quantify abundance requires an understanding of the many factors in the end-to-end remote sensing scenario from scene to sensor to data expl ...
