6. Gas in Scattering Media Absorption Spectroscopy in Large Geometries: Towards Monitoring Oxygen in Adult Lungs
University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionenAbstract : GAs in Scattering Media Absorption Spectroscopy (GASMAS) is a technique to study free gas inside strongly scattering bulk-materials. GASMAS is successful in safely measuring oxygen in lungs of neonates, with low-power tuneable diode-laser spectroscopy at 760 nm. READ MORE

7. An amplitude modulated laser rangefinder : electronic circuit design and implementation
University essay from Uppsala universitet/Signaler och systemAbstract : 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

8. E-Band SPDT RF Switch for a Class F PA in III-V Nanowire MOSFET Technology
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : This project designs an RF switch operating in E-band to provide a transmit path from a Class-F power amplifier (PA). The basic RF switch is based on the single-pole double-throw (SPDT) topology using shunt transistor switches and two λ/4 transmission line. READ MORE

9. An Inexpensive Alpha Spectrometer Based on a p-i-n Photodiode : Making Advanced Particle Detectors From Common Commercial Components
University essay from Uppsala universitet/Institutionen för materialvetenskapAbstract : The purpose of this project was to design, construct, and evaluate an alpha spectrometer based on an inexpensive p-i-n photodiode as a radiation detector. The BPX-61 p-i-n photodiode was selected and calculated to have a 93 µm wide sensitive volume at 25 V reverse bias. READ MORE
