Appl Spectrosc. 2015 Dec;69(12):1511-3. doi: 10.1366/14-07690.

A major type of infrared camera is sensitive to wavelengths in the 8-14 μm band and is mainly used for thermal imaging. Such cameras can also be used for general broadband infrared reflectance imaging when provided with a suitable...

Minimally invasive identification of degraded polyester-urethane magnetic tape using attenuated total reflection Fourier transform infrared spectroscopy and multivariate statistics.

Analytical chemistry

Cassidy BM, Lu Z, Fuenffinger NC, Skelton SM, Bringley EJ, Nguyen L, Myrick ML, Breitung EM, Morgan SL.

Anal Chem. 2015 Sep 15;87(18):9265-72. doi: 10.1021/acs.analchem.5b01810. Epub 2015 Aug 26.

Audio recordings are a significant component of the world's modern cultural history and are retained for future generations in libraries, archives, and museums. The vast majority of tapes contain polyester-urethane as the magnetic particle binder, the degradation of which...

Design of angle-tolerant multivariate optical elements for chemical imaging.

Applied optics

Appl Opt. 2002 Apr 01;41(10):1936-41. doi: 10.1364/ao.41.001936.

Multivariate optical elements (MOEs) are multilayer optical interference coatings with arbitrary spectral profiles that are used in multivariate pattern recognition to perform the task of projecting magnitudes of special basis functions (regression vectors) out of optical spectra. Because MOEs...

In Situ Methane Determination in Petroleum at High Temperatures and High Pressures with Multivariate Optical Computing.

Analytical chemistry

Jones CM, Price J, Dai B, Li J, Perkins DL, Myrick ML.
PMID: 31660727
Anal Chem. 2019 Dec 17;91(24):15617-15624. doi: 10.1021/acs.analchem.9b03715. Epub 2019 Nov 08.

Multivariate optical computing (MOC) is a compressed sensing technique enabling the measurement of analytes in a complex interfering mixture under harsh conditions. In this work, we describe the design, modeling, fabrication, and validation of a sensor for the measurement...

Rainfall statistics, stationarity, and climate change.

Proceedings of the National Academy of Sciences of the United States of America

Sun F, Roderick ML, Farquhar GD.
PMID: 29463723
Proc Natl Acad Sci U S A. 2018 Mar 06;115(10):2305-2310. doi: 10.1073/pnas.1705349115. Epub 2018 Feb 20.

There is a growing research interest in the detection of changes in hydrologic and climatic time series. Stationarity can be assessed using the autocorrelation function, but this is not yet common practice in hydrology and climate. Here, we use...

Fluorescence Excitation Spectroscopy for Phytoplankton Species Classification Using an All-Pairs Method: Characterization of a System with Unexpectedly Low Rank.

Applied spectroscopy

Rekully CM, Faulkner ST, Lachenmyer EM, Cunningham BR, Shaw TJ, Richardson TL, Myrick ML.
PMID: 29069908
Appl Spectrosc. 2018 Mar;72(3):442-462. doi: 10.1177/0003702817741278. Epub 2017 Nov 15.

An all-pairs method is used to analyze phytoplankton fluorescence excitation spectra. An initial set of nine phytoplankton species is analyzed in pairwise fashion to select two optical filter sets, and then the two filter sets are used to explore...

Oecologia

Roderick ML, Farquhar GD, Berry SL, Noble IR.
PMID: 28547064
Oecologia. 2001 Sep;129(1):21-30. doi: 10.1007/s004420100760. Epub 2001 Sep 01.

The volume of shade within vegetation canopies is reduced by more than an order of magnitude on cloudy and/or very hazy days compared to clear sunny days because of an increase in the diffuse fraction of the solar radiance....

Tuning D* with modified thermal detectors.

Applied spectroscopy

Simcock MN, Myrick ML.
PMID: 17217598
Appl Spectrosc. 2006 Dec;60(12):1469-76. doi: 10.1366/000370206779321481.

We report on the fabrication and characterization of a modified thermopile detector that has a spectral detectivity, D*, primarily determined by the absorbance of a polymer film. This was done by coating the detector with a metal mirror, followed...

Diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) detection limits for blood on fabric: Orientation and coating uniformity effects.
