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

Claim 0:
1. A system comprising:
a laser system configured to generate beams of light that include a probe beam of light;
a vapor cell sensor having a vapor therein and configured to allow the beams of light to pass through the vapor;
an optical detector configured to generate a detector signal based on the probe beam of light after the probe beam has passed through the vapor; and
a signal processing system configured to perform operations that comprise:
receiving the detector signal from the optical detector over a time period,
generating a digital signal based on the detector signal, the digital signal representing a measured response of the vapor to an RF field experienced by the vapor 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.
