  We advance and experimentally implement a protocol to generate perfect
optical coherence lattices (OCL) that are not modulated by an envelope field.
Structuring the amplitude and phase of an input partially coherent beam in a
Fourier plane of an imaging system lies at the heart of our protocol. In the
proposed approach, the OCL node profile depends solely on the degree of
coherence (DOC) of the input beam such that, in principle, any lattice
structure can be attained via proper manipulations in the Fourier plane.
Moreover, any genuine partially coherent source can serve as an input to our
lattice generating imaging system. Our results are anticipated to find
applications to optical field engineering and multi-target probing among
others.
