Phase-space analysis of transport of intensity equation under partially coherent illumination

Phase-space analysis of transport of intensity equation under partially coherent illumination

We introduced a generalized version of the transport of intensity equation from a partially coherent phase-space perspective that relates axial intensity derivative to the transverse divergence of the conditional frequency moment of the Wigner distribution function. This expression provides a powerf...
