  1. 1. Color Emotions without Blue Light : Effect of a Blue Light Filter on the Emotional Perception of Colors

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Maximilian Leefer van Leeuwen; [2023]
    Keywords : Emotional Response; Blue Light; Blue Light Filter; Color Constancy; Color Perception; Color Emotion;

    Abstract : Blue light filters have become commonplace in modern technology. While there has been a substantial amount of research into their effects on sleep, there has been little into the effect on the media perceived through them. READ MORE

  3. 2. High Contrast Imaging Through Scattering Media Using Structured Illumination Fourier Filtering

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

    Author : David Frantz; [2017]
    Keywords : scattering media; Structured Illumination; optical Fourier filtering; Modulation Transfer Function; Monte Carlo simulation; Technology and Engineering;

    Abstract : In imaging, obtaining high contrast is of great importance. When imaging through scattering media, optical filtering techniques are used to filter out multiple light scattering which causes loss of contrast. READ MORE

  4. 3. Broadband Photon Time-of-Flight Spectroscopy on Pharmaceutical Tablets and Dairy Products

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

    Author : Sören Johansson; [2015]
    Keywords : Compositional Analysis; Dairy; Tablets; Pharmaceutics; Scattering; Absorption; Spectroscopy; Photonics; Optics; Chemometrics; Partial Least Squares; PLS; Physics and Astronomy;

    Abstract : In this thesis, Photon Time-of-Flight Spectroscopy (PTOFS) is presented as a method to measure absorption and scattering spectra of turbid media samples in the near infra red wavelength range. In particular, absorption and scattering spectra measured on pharmaceutical tablets and dairy products are used to analyse the composition of the samples. READ MORE

  5. 4. Flow Cytometry Sensor System Targeting Escherichia Coli as an Indicator of Faecal Contamination of Water Sources

    University essay from Linköpings universitet/Teknisk biologi; Linköpings universitet/Tekniska högskolan

    Abstract : Poor water quality is a global health concern affecting one billion people around the world. It is important to monitor water sources in order to maintain the quality of our drinking water and to avoid disease outbreaks. READ MORE

  6. 5. Determination of Thermal and Blue Light Photochemical Hazard Protection needed by Automatic Welding filters

    University essay from Maskinteknik

    Author : Akoto Chama Leonel; [2009]
    Keywords : Thermal; Blue Light; Photochemical; Hazard; Protection; Automatic; Welding; Filters; Termisk; blått ljus; fotokemisk; risker; skydd; automatisk; svets; filter;

    Abstract : Recent developments in biological research, has shown that the initial maximum permissible exposure (MPE) limits for protection of workers from risks associated with artificial optical radiations were more stringent than needed. Using the most recent MPE limits for artificial optical radiation this piece of work was focused on the investigation of the level of visible light attenuation needed by automatic welding filters in case of switching failure.
