Polarised-depolarised Rayleigh scattering for simultaneous composition and temperature measurements in non-isothermal gaseous mixtures

Documentation:
The data was collected between February 2018 and May 2019. The data stored are raw image (.tif) files, some experimentally-acquired, and some software-generated. There are 3 main datasets. The first of these are from polarised-depolarised Rayleigh scattering experiments conducted on a gaseous mixture of CO2 and N2. Data was collected from two opposite facing cameras imaging a single area of interest where a mixture of gases was illuminated with a laser sheet. The goal of this experiment was to demonstrate PDRS as a plausible optical diagnostic technique for non-isothermal gaseous mixtures. The second dataset was obtained by taking pictures of a white wall using varying lens apertures. This was to obtain an estimate for the shot noise characteristic of the camera, which could then be used in a numerical sensitivity analysis. The final dataset consists of an arbitrary 2D mixture fraction and temperature field (in image form), also used in the numerical sensitivity analysis. These images were produced using Paint.
