Far-Field Raman–Nath Diffraction of Polychromatic Light and a Ternary Data Transmission Scheme

Raman–Nath diffraction is produced by a thin acoustic beam. The standing sound wave acts as a thin phase grating, causing monochromatic light to interact with it and diffract into multiple orders. This phenomenon is typically used to redistribute light intensity at specific angle...
