  • Identification of forensic fabrics using a portable Raman spectrometer

    At a crime scene, a police officer collects a fiber sample that may prove to be invaluable evidence in identifying a criminal or exonerating an innocent person. While FTIR has been used for analysis in the past, the strong absorption of the fabric or the glass slide where it is mounted makes the spectrum very hard to interpret. In recent years, Raman spectroscopy has been studied extensively for ...

  • Spatial and temporal sampling of ecosystem optical properties with the UniSpec-DC

    Satellite sensors (e.g. MODIS) provide large spatial patterns with regional or global coverage (Chen, 1999). However, the coarse resolution of satellite sensors are sometimes problematic, particularly for patchy landscapes (Turner et al., 2003). To properly validate and interpret satellite imagery, additional ground remotely sensed and biophysical data are needed. The UniSpec-DC (PP Systems, ...

  • Overview of Rotating Disc Electrode (RDE) Optical Emission Spectroscopy for In-Service Oil Analysis

    Introduction The basis of modern oil analysis is the use of optical emission spectroscopy (OES) to measure the ppm (parts per million) levels of wear metals, contaminants and additives in oil samples. Whatever else an oil lab may measure, a multi-elemental analysis is the core of in-service oil analysis. This paper gives an overview of Rotating Disc Electrode Elemental Spectroscopy and its ...

  • Measuring IR Light and Near-IR Light

    Infrared (IR) light emits a broad range of non-visible wavelengths in the electromagnetic spectrum. Applications for infrared, including near-infrared, are defined by the respective IR bands during output. For example, LIDAR (Light Detection and Ranging) equipment uses 1,000 nm and 1,550 nm IR bands while surveying an area. In the military sector, 850 nm, 1,060 nm and 1,500 nm (and up) are used ...
