Abstract: In a general aspect, a system is described herein for detecting the phase properties of a radio frequency (RF) wave. The system includes a vapor cell sensor that contains a vapor and is configured to generate an optical signal in response to laser signals that interact with the vapor. The vapor has a Rydberg electronic transition that interacts with a target RF electromagnetic field, and the optical signal is based on a transmission of one of the laser signals through the vapor. The system also includes an optical detection system and a signal processing system. The optical detection system is configured to generate a detector signal in response to receiving the optical signal, and the signal processing system is configured to receive the detector signal and perform operations that determine a phase change of the target RF electromagnetic field.

Abstract: In a general aspect, a radiometer is disclosed that includes a vapor cell sensor. The vapor cell sensor contains a vapor and is configured to generate an optical signal in response to laser signals and thermal radiation interacting with the vapor. The vapor includes a Rydberg electronic transition that is configured to interact with the thermal radiation. The radiometer also includes a computing system having one or more processors and a memory. The memory stores instructions that, when executed by the one or more processors, are configured to perform operations that include generating, based on the optical signal, transmission data that represents the transmission of the one laser signal through the vapor. The operations also include determining, based on the transmission data, a temperature of a target body that generates the thermal radiation.

Abstract: In a general aspect, a method is described herein for detecting the phase properties of a radio frequency (RF) wave. The method includes generating an optical signal by interacting laser signals with a vapor of a vapor cell sensor. The optical signal is based on a transmission of one of the laser signals through the vapor. The method also includes altering an intensity of the optical signal by interacting a target RF electromagnetic field with a Rydberg electronic transition of the vapor. The target RF electromagnetic field includes a time series of RF pulses. The method additionally includes determining, by operation of a signal processing system, a magnitude of phase change in the time series of RF pulses. In some implementations, the method includes determining a phase of a target RF pulse in the times series of RF pulses.
