Structured light illumination for order sorting in Echelle spectrometers [PDF]
Optics Express, 2017 We report on the operation of an echelle spectrometer under structured light illumination. Each diffraction order of the spectrometer is encoded with a certain periodic structure allowing for order sorting by numerical analysis after detection.

Influence of Sample Preparation Methods for Porcine Tissue: Calibration-Free LIBS for In Vivo Applications. [PDF]
J BiophotonicsThis study examined whether the preparation of samples for CF‐LIBS influences the results of measurements taken on biological samples. Porcine skin, muscle and fat were analysed. Some samples were cut with a scalpel, some were sectioned using liquid nitrogen and some were embedded in PBS or deionised water.
