  1. 11. Diffuse correlation spectroscopy for estimation of coagulation thickness : a phantom study

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Zeyneb Alsadi; [2019]
    Keywords : DCS; Diffuse correlation spectroscopy; Biomedical optics; coagulation; phantom study; coagulation depth; coagulation thickness; diffusion; model; two layer model;

    Abstract : The objective of this preliminary study was to determine the potential of diffuse correlation spectroscopy (DCS) for assessment of coagulation depth. Coagulation of tissue can occur due to a number of different reasons such as thermal or electrical burns or radiofrequency ablation. READ MORE

  2. 12. Noncollinear optical parametric amplification of a supercontinuum

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

    Author : Henrik Åkesson; [2019]
    Keywords : optical parametric amplification; supercontinuum generation; nonlinear optics; laser pulse compression; lasers; optics; Physics and Astronomy; Technology and Engineering;

    Abstract : During this thesis, work has been done towards realizing a short-wave infrared (SWIR) laser source based on optical parametric amplification. It is planned that this setup should be able to produce few-cycle laser pulses at 2μm with a stable carrier-envelope phase (CEP). READ MORE

  3. 13. Modelling of Hand Gestures and Motions

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Erik Ingemarsson; [2019]
    Keywords : Radar; Gesture Recognition; Signal Processing; Technology and Engineering;

    Abstract : Measuring the radar response has proven to be a valid input for neural networks used for gesture and motion recognition. Previous work have been based on measuring the radar response of hand gestures, but it has been shown that models based on the analytic expressions for basic objects are useful when simulating larger motions, such as pedestrians.

  4. 14. Design of an X-ray transfer beamline for the Soft X-ray project at MAX IV

    University essay from

    Author : Milad Emadi; Sofia Tynelius; Patric Beas Peterson; Johnny Ljung; [2019]
    Keywords : optics; focusing; beam; x-ray; MAX-IV; soft x-ray; transfer; matrix;

    Abstract : At the MAX-IV lab in Lund, there is a current goal to build a new soft X-Ray laser. The beam will be generated from a free-electron laser (FEL), which is an instrument consisting of high-speed electrons. The electrons move through alternating magnetic fields, causing the beam to become monochromatic. READ MORE

  5. 15. I-V and Optical Characterization of InP/InAsP Quantum Disc-in-Nanowire Infrared Photodetectors

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Divya Raval; [2019]
    Keywords : Nanowires; Infrared photodetectors; Quantum disc; Photocurrent;

    Abstract : Photodetectors are semiconductor devices capable of converting optical signals into electrical signals. There is a wide range of applications for photodetectors such as fiber optics communication, infrared heat camera sensors, as well as in medical and military equipment. READ MORE
