Digital Phase Technology: working principle

Measuring variation of EM field intensity

Coupling the intensity variation to the phase

Scaling the phase to represent the 3D image

The light propagation is formally described by the electric and magnetic vectors that fluctuate in directions perpendicular to each other and to the direction of the beam.

These vectors satisfy a set of fundamental Maxwell partial differential equations describing how the variation in the electric vector influences the value of the magnetic field vector, and vice versa.

The PhaseView® numerical technology relies on efficient methods of solving systems of differential equations that govern the light energy propagation that is described by the vector quantity, the Poynting's vector.

This technology decouples the spatial variation of the electromagnetic power and the 3D shape of the illuminated object. The phase information is required to reconstruct the 3D shape of the measured object.
