  1. 1. Analysing the controls over DOM quality in two contrasting sub polar marine environments

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Chiara Monforte; [2020]
    Keywords : DOM optical properties; Absorbance; Fluorescence; EEMs; Burdwood Bank; Beagle Channel; Earth and Environmental Sciences;

    Abstract : In this study, Dissolved Organic Matter (DOM) quality was analysed through its optical properties. Samples from the estuarine waters of the Beagle Channel and oceanic ones of the Burdwood Bank were examined in order to understand how DOM quality was changing. READ MORE

  2. 2. Mapping an Auditory Scene Using Eye Tracking Glasses

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Reglerteknik

    Author : Alfred Fredriksson; Joakim Wallin; [2020]
    Keywords : Sensor Fusion;

    Abstract : The cocktail party problem introduced in 1953 describes the ability to focus auditory attention in a noisy environment epitomised by a cocktail party. An individual with normal hearing uses several cues to unmask talkers of interest, such cues often lacks for people with hearing loss. READ MORE

  3. 3. Phase control with spatial-light modulators towards application for opto-optical modulation

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Isa Hendriks; [2020]
    Keywords : phase control; spatial-light modulator; simulation; spatial phase profile; opto-optical modulation; Physics and Astronomy;

    Abstract : This project is about focusing a Gaussian laser beam that has a spatial phase profile applied by a spatial light modulator. The goal is to be able to control the shape, position and phase of the peak at the focus and to split up the peak at the focus into several peaks. READ MORE

  4. 4. Simulation of Optical Aberrations for Comet Interceptor’s OPIC Instrument

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Maximilian Bührer; [2020]
    Keywords : simulation; camera; lens effects; optical aberrations; optics; ray tracing; sensor noise; coma; astigmatism; chromatic aberration; motion blur; rolling shutter; CMOS; CCD;

    Abstract : In space exploration optical imaging is one of the key measurements conducted, with a vast majority of missions heavily relying on optical data acquisition to examine alien worlds. One such endeavor is ESA’s F-class mission Comet Interceptor, a multi-element spacecraft expected to be launched in 2028. READ MORE

  5. 5. Accurate Abundances of Giant Stars in the Local disk: A manual analysis of IR APOGEE spectra

    University essay from Lunds universitet/Astronomi; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Ivalu Barlach Christensen; [2020]
    Keywords : Galactic Chemical Evolution; Astrophysics; Astronomy; IR Spectroscopy; Milky Way; Abundance; Physics and Astronomy;

    Abstract : Purpose: In order to study the Galactic Chemical Evolution, elemental abundances are needed. The purpose of this work is to investigate the chemical evolution of the Milky Way by determining several elemental abundances of giants in the local disk. READ MORE
