Step 2

Step 2: Relate intensity variation as light propagates in 3D space and & phase of the light beam.

Acquisition of images is performed in the 3D space by 2D digital sensors (cameras). The fundamental difference of the 2D case from the 1D one is that the energy flux is not constrained to one direction: indeed, light energy may circulate in the 2D space.

The energy circulation and redistribution in the light propagation direction is described by a system of differential equations.

Starting from the fundamental electromagnetic differential equations, PhaseView numerical technology relates the spatial variation of the electromagnetic power and the phase of the optical wave.
