Tomographic investigation of the refractive index profiling using speckle photography technique

A multiple-exposure speckle photography technique has been applied to record the deflection angle of light travelling through hot air around a candle flame for different viewing angles (projections) along a line for each of eight specklegrams. The obtained data has been used to provide input data fo...

Description
Summary:A multiple-exposure speckle photography technique has been applied to record the deflection angle of light travelling through hot air around a candle flame for different viewing angles (projections) along a line for each of eight specklegrams. The obtained data has been used to provide input data for the tomographic reconstruction program to construct a three-dimensional refractive index distribution.
