Abstract
A chip scale atomic clock (CSAC) accelerometer incorporates a case in which a cesium vapor resonance cell is carried. An optical laser is mounted in the case and emits a laser beam through the resonance cell. The laser is modulated by a microwave signal generator. A photon detector mounted in the case receives photons emitted by cesium atoms in the resonance cell and provides a frequency output representative of interference of energy levels of the emitted photons including momentum changes due to acceleration.
