  Stokes polarimetry is widely used to extract the polarisation structure of
optical fields, typically from six measurements, although it can be extracted
from only four. To measure the required intensities, most approaches are based
on optical polarisation components. In this work, we present an all-digital
approach that enables a rapid measure of all four intensities without any
moving components. Our method employs a Polarisation Grating (PG) to
simultaneously project the incoming mode into left- and right-circular
polarised states, followed by a polarisation-insensitive Digital Micromirror
Device (DMD), which digitally introduces a phase retardance for the acquisition
of the remaining two polarisation states. We demonstrate how this technique can
be applied to measuring the SoP, vectorness and intra-modal phase of optical
fields, without any moving components and shows excellent agreement with
theory, illustrating fast, real-time polarimetry.
