Abstract
A light pulse is emitted from a light source for illuminating a medium. Energy level data of the light pulse is measured before the light pulse enters the medium. An image sensor captures an image that includes an interference pattern generated by an exit signal of the light pulse exiting the medium interfering with a reference wavefront. Normalized intensity data is generated by normalizing intensity data exit signal data by the energy level data.
