Doubly positive functions in coherent and partially coherent optics
Optics Letters, 2017A function is said to be doubly positive if it is everywhere non-negative and the same holds true for its Fourier transform. After discussing applications to coherent and partially coherent fields, we present examples and properties of such functions together with procedures to devise classes of them.

When discussing the theory of interference and diffraction of waves, one usually assumes that the fields remain perfectly sinusoidal for all values of time. This is obviously an idealized situation and we know that the radiation from an ordinary light source consists of finite* size wave trains, a typical time variation of which is shown in Fig.
