Simple coherence measurement with a modified Lau interferometer.
We measure mutual intensity in quasi-monochromatic light. Our setup is simple, without a lens. A rotating grating and a one-dimensional receiver are the only pieces of hardware. The action of our system can be understood as that of a mock Lau interferometer.
