1. Geological characterization of rock samples by LIBS and ME-XRT analytical techniques
University essay from Luleå tekniska universitet/Geovetenskap och miljöteknikAbstract : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. READ MORE

2. Dispersion management and characterization of ultrashort laser pulses for the optimization of parametric processes
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : This thesis set out to continue the development of a short-wave infrared (SWIR) optical parametric amplifier (OPA). The system is based on a Yb-ber chirped pulse amplification (CPA) laser delivering 400 fs long pulses, centered around 1030 nm, at 200 kHz repetition rate and 40 W average power. READ MORE

3. UAV based hyperspectral grassland monitoring in an alpine shallow erosion area : lessons learnt from classifying vegetation indicating shallow erosion risk
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : UAV based hyperspectral grassland monitoring in an alpine shallow erosion area Recent research in the Alps found that a reduction in grassland management is correlated to an increase in a certain type of shallow erosion areas called blaiken. This change also entails changes to the dominant grassland vegetation. READ MORE

4. Characterization of an On-chip Photonic Waveguide gas Sensor
University essay from KTH/Skolan för teknik och hälsa (STH)Abstract : Gas sensing in medical applications requiresmall, precise and sensitive sensors. This projecthas developed a laboratory setup for characterisationof a waveguide-based gas sensor for carbon dioxide andmethane working in the mid-IR range of 2 - 10 μm. Thissetup utilizes an IR-camera to image the waveguideswhen a mid-IR laser is coupled into them. READ MORE

5. Evaluation and Characterization of a Logarithmic Image Sensor
University essay from Lunds universitet/Avdelningen för Biomedicinsk teknikAbstract : In this thesis, issued by Axis Communications AB, a CMOS-type image sensor with a logarithmic response and wide dynamic range capabilities was evaluated and char- acterized with respect to signal response and noise characteristics. The evaluation was performed in the context of the need for wide dynamic range imaging in video surveillance. READ MORE
