CPC G01S 3/46 (2013.01) | 20 Claims |
1. A microwave direction finder comprising:
a cell containing molecules;
a laser system including:
a probe laser that provides a probe beam that transitions the molecules from a ground state to an excited state; and
a control laser that provides a control beam that transitions the molecules in the excited state to a laser-induced Rydberg state;
a microwave lens system including plural microwave lenses that convert a microwave wavefront into respective microwave beams, the microwave lens system causing at least a pair of the microwave beams to counter-propagate through the molecules so as to create a microwave interference pattern that is imposed on the probe beam to form a probe transmission pattern in the probe beam, the probe transmission pattern having a position along a direction of counter-propagation within the cell; and
an analysis system that determines a propagation direction of the microwave wavefront based on the position of the probe transmission pattern.
