WebApr 11, 2024 · In Section 2, we discuss a simple, heuristic treatment of the Lau effect, by using a tunable magnification. In Section 3, we formalize the heuristic geometrical optics treatment, by using scalar diffraction in the paraxial regime. In Section 4, we use a grating coded with the Barker sequences, for achieving Lau patterns with narrow peaked profiles.
