The invention relates to a millimeter wave and terahertz wave electric field measurement method, device and system, and the method comprises the steps: obtaining an amplification value of a standing wave in an atomic bubble cavity on the amplitude of an electromagnetic wave, determining a correction coefficient, then moving the measurement value determined by a standing wave period in a glass probe along the diameter direction according to detection light, and finally, correcting the measurement value according to the correction coefficient to obtain the millimeter wave and terahertz wave electric field values. On the basis, the millimeter wave electric field value and the terahertz electric field value are obtained after the measurement value is corrected through the correction coefficient, interference caused by the standing wave phenomenon can be reduced, and the measurement accuracy of the millimeter wave electric field value and the terahertz electric field value is improved.
Description
technical field [0001] The invention relates to the field of measurement technology, in particular to a method, device and system for measuring millimeter wave and terahertz wave electric fields. Background technique [0002] Millimeter waves refer to electromagnetic waves whose wavelength range is on the order of millimeters and whose corresponding frequency ranges from tens of GHz to hundreds of GHz. Terahertz wave (TeraHertz, THz) frequency band refers to the electromagnetic radiation area with a frequency ranging from a few tenths to a dozen THz, which is quite wide between millimeter waves and infrared light. The development of THz and millimeter wave field strength measuring instruments and equipment is relatively slow due to the high technical difficulty, resulting in a relatively lagging behind in this technology research. The precise measurement of electromagnetic field strength and polarization direction has great research significance in communication, remote sen...
