Berry (PB) devices with arbitrary wavefronts, via photo-patterning an azo-dye doped LC with
a two-dimensional linear polarization field, whose local polarization direction can be
controlled by a spatial light modulator (SLM) on the pixel level. Upon one exposure, different
local LC orientations are generated simultaneously. The non-interferometric approach is
insensitive to environmental disturbance, and moreover, the dynamic phase mask on the …
