System for analyzing electromagnetic radiation

A system for analyzing electromagnetic radiation, comprising:

• an enclosure filled with gas containing atoms of a known type;
• at least one light source emitting light capable of exciting the atoms of the known type in the gas;
• a source of the electromagnetic radiation to be analyzed arranged such that the emitted electromagnetic radiation acts on the atoms of the known type in the gas;
• and
• a sensor for capturing an intensity of transmission of the light emitted by and/or from the at least one light source passed through the gas,
• wherein the system further comprises an electrical field source and/or magnetic field source configured to establish a predefined electrical field and/or magnetic field acting on the atoms of the known type in the gas, such that the light captured by the sensor reflects a response of the atoms of the known type in the gas on the electrical and/or magnetic field, the light from the at least one light source and the electromagnetic radiation to be analyzed,
• wherein the sensor is a two-dimensional imaging device producing an at least two-dimensional image of the light emitted by and/or from the at least one light source passed through the gas,
• wherein the two-dimensional image reflects frequency information and a gradient of intensity for improving a dynamic range.
