Assignee: QUANTUM VALLEY IDEAS LABORATORIES
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 9:
10. A method comprising:
passing beams of light through a vapor in a vapor cell sensor, the beams of light comprising a probe beam of light;
allowing an RF field to interact with the vapor;
generating, by operation of an optical detector, a detector signal that is based on the probe beam of light after the probe beam has passed through the vapor;
receiving the detector signal at a signal processing system over a time period; and
by operation of the signal processing system:
generating a digital signal based on the detector signal, the digital signal representing a measured response of the vapor to the RF field over the time period,
applying a matched filter to the digital signal to generate a filtered signal, the filtered signal generated based on a comparison of the digital signal with a response template, the response template representing a known response of the vapor to a target RF pulse, and
processing the filtered signal to determine properties of the RF field experienced by the vapor over the time period.
