1. 1. Development of a QRNG front-end for shot noise measurement : analysis of quantum shot noise originating from photodiodes

   University essay from Linköpings universitet/Informationskodning

   Author : Martin Clason; [2023]
   Keywords : shot noise; quantum random number generator; photodiode; transimpedance amplifier; skottbrus; kvantslumptalsgenerator; fotodiod; transimpedansförstärkare;

   Abstract : As one of the more mature quantum technologies, quantum random number generators (QRNGs) fill an important role in producing secure and private keys for use in cryptogra- phy in e.g. quantum key distribution (QKD) systems. Many available QRNGs are expen- sive and optical QRNGs often require complex optical setups. READ MORE

3. 2. An amplitude modulated laser rangefinder : electronic circuit design and implementation

   University essay from Uppsala universitet/Signaler och system

   Author : Fazel Naser; Stefan Morin; [2022]
   Keywords : Amplitude modulation; Phase shift; Laser rangefinder; Drive electronics; PCB; Colpitts crystal oscillator; Transimpedance amplifier;

   Abstract : This report describes the design and implementation of a prototype for an amplitude modulated laser rangefinder, which is made on a PCB consisting of a laser module emitting light, a photodiode receiving the light reflected from the target, and other components. The design is made for the different power levels, generation of the modulation output and the reception of the signal. READ MORE

4. 3. System Model of an Ultra-LowPower Fluorescence Detection Micro-Device

   University essay from Linköpings universitet/Elektroniska Kretsar och System

   Author : Yuanyuan Xue; [2020]
   Keywords : ;

   Abstract : This thesis aims to explore the power consumption limits of Complementary Metal-Oxide-Semiconductor (CMOS) fluorescent biosensors that meet the demand, a Matlab-based calculator is designed, in which users can input required system parameters (such as LED power and noise) to observe the minimum power consumption of each basic component and the constraints of the transimpedance amplifier: cut-off frequency, signal- to-noise ratio, dynamic range, etc. Thereby to provide a reference range for the next level designs of each component in the detection system.

5. 4. Short-Wave Infrared Lidar on Atmospheric Aerosols and Insects

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

   Author : Mariam Andersson; [2017]
   Keywords : Lidar; Scheimpflug; Time-of-Flight; Remote sensing; Atmospheric sensing; Physics and Astronomy;

   Abstract : This thesis focusses on the implementation of two elastic lidar (light detection and ranging) techniques for the monitoring of atmospheric aerosols and insects at short-wave infrared wavelengths. Data acquisition software was developed for a time-of-flight system, housed in the Lund University Mobile Biosphere Observatory (LUMBO), with consideration to the intended entomological application.
