摘要： One example includes an electrometer system. The system includes a sensor cell comprising alkali metal atoms within, and an optical beam system configured to provide at least one optical beam through the sensor cell to provide a first Rydberg energy state of the alkali metal atoms, the at least one optical beam exiting the sensor cell as a detection beam. The system also includes a radio frequency (RF) tuning field generator configured to generate an RF tuning signal having a tuning frequency that is equal to an energy difference between the first Rydberg energy state and a second Rydberg energy state of the alkali metal atoms. The system further includes a detection system configured to monitor the detection beam to detect an external signal having a frequency that is between the first and second Rydberg energy states.

摘要： A method for presence detection in an environment to be monitored, includes generating an electric charge signal in a condition of absence of presence in the environment to be monitored. An electric charge signal is generated in an operating condition in which a person may be present in the environment. The two generated signals are processed and the results of the processing are compared. Processing the signals includes representing in a biaxial reference system the value of the charge signal considered and its derivative with respect to time, and identifying a plurality of points in the reference system. By comparing the position of the points acquired during the possible human presence with those of the base shape, a variation indicating the actual human presence may be detected. In this case an alarm signal is generated.

摘要： An observation apparatus includes a laser light source, a scanning optical system irradiating a semiconductor device with laser light output from the laser light source, a bias power supply applying a reverse bias voltage of a predetermined voltage between electrodes of the semiconductor device, a sensor detecting an electrical property occurring in the semiconductor device in response to the laser light, and a control system generating an electrical property image of the semiconductor device based on a detection signal from the sensor. The bias power supply gradually increases a magnitude of the predetermined voltage until the predetermined voltage reaches a voltage at which avalanche amplification occurs in the semiconductor device. When the predetermined voltage is increased, the scanning optical system irradiates with the laser light, the sensor detects the electrical property, and the control system generates the electrical property image.

摘要： A method for measuring electric potential difference comprises following steps. A carbon nanotube composite layer is located on an object and electrically connected to a first region and a second region spaced from each other in the object, wherein an unknown electric potential difference U exists between the first region and the second region. Characteristic band frequency value Y* of Raman-spectra of the carbon nanotube composite layer under the unknown electric potential difference U is measured. A relationship between the characteristic band frequency value Y of Raman-spectra and the electric potential difference ΔU of the carbon nanotube composite layer is obtained. Value of unknown electric potential difference U is obtained through the relationship between the characteristic band frequency value Y of Raman-spectra and the electric potential difference ΔU.
