Claim 10:
11. A device for optically measuring a cross-movement profile, comprising:
a receiver comprising a single physical photodiode representing a single pixel and adapted to analyze electromagnetic radiation traveling through a medium, wherein the single physical photodiode is subdivided into a plurality of distinct sub-pixel detection portions, wherein each sub-pixel detection portion simulates a separate physical photodetector, wherein sub-pixel detection portion is configured to receive, over time and from a substantially common direction, a plurality of snapshots of a moving scintillation pattern created by eddies in the medium diffracting and refracting electromagnetic radiation, and wherein, for each sub-pixel detection portion, converting each received snapshot into a single data point measuring cumulative light intensity; and
the device configured to compare cumulative light intensities from each sub-pixel detection portion and to generate a cross-movement profile within the medium, the generation of the cross-movement profile a function of particular spacing between, and a size of, each of the plurality of distinct sub-pixel detection portions.
