From: Modal beam splitter: determination of the transversal components of an electromagnetic light field
The experimental set-up consists of a Laguerre-Gaussian beam generating section (top), and a modal beam splitter section (bottom). The light field of the beam generator, shown in red, is assumed to be unknown when it connects to the input port of the modal beam splitter light path, shown in green to emphasize the distinction. L1-3: positive lenses of increasing focal length, PH: pinhole, LP: linear polarizer, λ/2: half-wave plate, ND: neutral density filter, DM: dielectric mirror, CCD: Charge Coupled Device, and A-SLM and P-SLM indicate amplitude and phase modulators respectively.
