Single-Beam Multidimensional Coherent Spectroscopy
Multidimensional coherent spectroscopy (MDCS) is a set of laser techniques that nondestructively measures how evolving matter absorbs and emits light. The information present in a multidimensional spectrum is both extensive and straightforward to interpret, and MDCS provides valuable information on materials, chemicals, and biological systems.

Growing Developments with NIR Spectroscopy
Advancements to NIR LED emitters are helping to grow the product portfolio for mobile spectroscopy and opening new application fields for well-being and health monitoring. Consumers will soon be able to use their smartphones to check the freshness of supermarket food, measure the calories in restaurant meals, and verify whether a medication is valid and contains its prescribed contents.

Compact Laser Detects Greenhouse Gases Using Mid-IR Source
A system developed at École Polytechnique Fédérale de Lausanne, composed of a standard laser and a photonic chip, uses a mid-infrared light source to detect greenhouse and other gases. The team took a commercially available fiber laser and combined it with a waveguide chip to reliably generate lightwaves in the MIR spectrum.

Spectroscopic OCT: Seeing Under the Skin with Depth-Resolved Spectroscopy
Tue, May 14, 2019 1:00 PM - 2:00 PM EDT
This webinar, presented by Adam Wax, Ph.D., will introduce new methods for evaluating skin injury using spectroscopic measurements based on coherence imaging. These methods were developed by Wax and his group at the Biomedical Interferometry, Optics and Spectroscopy (BIOS) lab at Duke University. Wax will discuss spectroscopic OCT (SOCT), an extension of OCT technology for analyzing structural as well as spectroscopic information. He will present his lab’s application of SOCT for burn injuries and also address SOCT’s potential in the area of cancer detection.
