Phase contrast techniques in the conventional optical microscope are partially coherent in nature. A few of these methods, in particular differential interference contrast, and differential phase contrast, are introduced, and their optical properties compared. Partially coherent imaging can be simulated based on a phase space model. The Wigner function of the object transmission can be regarded as a measure of local phase gradient, analogous to an instantaneous frequency, thus justifying the physical basis of the Wigner approach.
