1. A sensor system, comprising:
a laser source configured to emit a pump beam at a first wavelength and a probe beam at a second wavelength;
optical means for receiving the pump beam and the probe beam from the laser source, the optical means operative to generate a plurality of light beams, each having a different frequency, from the pump beam and the probe beam;
one or more cells configured to receive one or more of the light beams from the optical means and to allow passage of the one or more of the light beams therethrough, the one or more cells containing a plurality of alkali atoms, wherein the alkali atoms in the one or more cells are excitable to a manifold of Rydberg energy levels by the one or more of the light beams;
a dichroic filter configured to receive the one or more of the light beams from the one or more cells, the dichroic filter operative to separate pump beam light and probe beam light from the one or more of the light beams; and
a detector array configured to receive the probe beam light from the dichroic filter, the detector array including a two-dimensional array of photosensors operative to map out transmission of respective light beams corresponding to the probe beam light through the one or more cells.
