1. 1. Identification of Environmental Plastic Samples from a Caribbean Beach Survey by Near-Infrared Spectroscopy with the MicroNIR and Chemometric Analysis

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : David Vigren; [2015]
   Keywords : MicroNIR; Near-infrared spectroscopy; Chemometrics; Plastic polymer identification; Environmental plastic beach survey;

   Abstract : MicroNIR is a portable near-infrared diffuse reflection spectroscope. Its suitability for identifying environmental plastic polymers was evaluated through a series of performance tests. The plastic samples were collected during a beach survey in the Caribbean. First a reference database was built by analysing a series of reference plastic polymers. READ MORE

3. 2. Blood interference in fluorescence spectrum : Experiment, analysis and comparison with intraoperative measurements on brain tumor

   University essay from Linköpings universitet/Biomedicinsk instrumentteknik; Linköpings universitet/Tekniska högskolan

   Author : Shannely Lowndes; [2010]
   Keywords : autofluorescence; blood absorption spectra; diffuse reflection spectroscopy; optical touch pointer; intraoperative optical measurements;

   Abstract : The optical touch pointer (OTP), a fluorescence spectroscopy based system, assists brain surgeons during guided brain tumor resection in patients with glioblastoma multiforme (GBM). After recording and analyzing the autofluorescence spectrum of the tissue, it is possible to distinguish malignant from healthy brain tissue. READ MORE
