21. Performance Studies and Star Tracking for PoGOLite
Sammanfattning : PoGOLite is a balloon-borne experiment, which will study polarized soft γ-ray emissionfrom astrophysical targets in the 25-80 keV energy range by applying well-typephoswich detector technology. Polarized γ-rays are expected from a wide variety of sources including rotation-powered pulsars, accreting black holes and neutron stars,and jet-dominated active galaxies. LÄS MER
22. Colorimetric and Multispectral Image Acquisition
Sammanfattning : The trichromatic principle of representing color has for a long time been dominating in color imaging. The reason is the trichromatic nature of human color vision, but as the characteristics of typical color imaging devices are different from those of human eyes, there is a need to go beyond the trichromatic approach.

23. Combustion Engine Characterization and Development by Means of Laser Diagnostics
Sammanfattning : Planar laser induced fluorescence (LIF) has been utilized for two-dimensional imaging in combustion environments. By using tracer LIF the fuel distribution prior to ignition has been monitored in a GDI-engine. LÄS MER
24. Optical diagnostics of Soot in optically dense sprays
Sammanfattning : Soot diagnostics in engines can be carried out with optical methods that have the potentialfor high temporal and spatial resolution. Some of these methods were appliedto study diesel spray combustion in the Chalmers High Pressure, High Temperature(HP/HT) spray rig. LÄS MER
25. On the Use of Laser-Induced Incandescence for Soot Diagnostics: From Theoretical Aspects to Applications in Engines
Sammanfattning : The laser-induced incandescence technique (LII) is a laser-based diagnostic technique for measurements of soot volume fraction and particle size. The technique relies on detection of incandescent light from soot particles heated to around 4000 K using nanosecond laser pulses. LÄS MER
