1. An atomic sensor system comprising:
an optical source configured to provide an optical beam;
a plurality of sensor cell systems, each of the sensor cell systems comprising sensing media enclosed in a volume therein;
optics comprising a plurality of beamsplitters configured to provide a portion of the optical beam to each of the sensor cell systems to provide interaction of the optical beam with the sensing media in each of the respective sensor cell systems, the respective portion of the optical beam exiting each of the sensor cell systems as a respective detection beam; and
a detection system comprising at least one photodetector configured to receive the detection beam from each of the sensor cell systems and to determine a measurable parameter based on an optical characteristic associated with the detection beam from each of the sensor cell systems.
