Igor Gornushkin and colleagues at BAM Federal Institute for Materials Research and Testing in Berlin, Germany studied the feasibility of using optical spectroscopy as a control method for laser metal deposition, and he recently spoke to us about this work. Gornushkin is the 2022 recipient of the Lester W. Strock Award from the New England Chapter of the Society for Applied Spectroscopy (SAS).

A frequency comb is a laser source, with evenly spaced narrow lines, potentially useful for spectroscopy applications, particularly as a source or for alignment of the wavelength axis.

The Optics Physics app is designed to serve as a pocket dictionary of all optical characteristics and their analyses, with formulas to find various parameters.

Dr. Richard R. Hark, a professor in the Department of Chemistry at Juniata College in Huntingdon, Pennsylvania, discusses his work with LIBS in applications such as forensic science, conflict minerals, and geochemical fingerprinting.

The choices for LIBS hardware are discussed in detail, particularly lasers and spectrometers, and the trade-offs between cost, size, and performance are illustrated.

Improvements in engineering and manufacturing processes and tools have rapidly lowered the cost to make products, and to distribute them. The next generation of optical sensing technologies will offer a framework for the creation and testing of new business models based upon the distribution of knowledge and service. In fact, this concept of "distributed sensing" already has emerged in networked systems monitoring various aspects of the environment.
