Fig. 2

a Schematic of the AOLG configuration. Attenuator: variable optical attenuator; L: focal lens; Lm: movable focal lens fixed on a translation platform; BS: beam splitter. b Dependence of ‘1’ and ‘0’ logical states on phase shifts. rnear-field: the radial coordinates near the focal plane. rfar-field: the radial coordinates near the CCD.
