Internal defect scanning of sweetpotatoes using interactance spectroscopy

PLOS ONE, 16(2).

By: M. Kudenov n, C. Scarboro  n, A. Altaqui n, M. Boyette n, G. Yencho  n & C. Williams n 

MeSH headings : Ipomoea batatas; Plant Diseases; Plant Tubers; Spectroscopy, Near-Infrared
TL;DR: It is demonstrated that interactance spectroscopy can detect the unique near-infrared optical signatures of necrotic tissues in sweetpotatoes down to a depth of approximately 5±0.5 mm and that light scattering measurement methods will represent a significant improvement over the current destructive analysis methods used to assay for internal defects inSweetpotatoes.

Thermal stabilization of a fiber-based channeled spectropolarimetry

OPTICAL ENGINEERING, 58(12).

By: A. Altaqui n & M. Kudenov n

author keywords: spectropolarimetry; optical fiber; spectroscopy; polarimetry; optical metrology
TL;DR: This work presents a calibration technique for fiber-based CSP that leverages phase-shifting interferometry (PSI) to acquire and demodulate the fiber’s retardation phase accurately and demonstrates that the PSI calibrations offer higher stability and accuracy, at different optical fiber temperatures, as compared to reference-beam calibrations.
