Abstract: Provided are a cooperative polarization skylight background radiation measurement device and method, belonging to the field of polarized radiation remote sensing. The device includes a measurement probe, a lower computer control system, a two-dimensional turntable, a base and data transmission interface, as well as an upper computer. The method includes the following steps: the cooperative skylight background radiation polarization measurement device is initialized, a polarization wheel is returned to a zero position, and dark noise is collected by a double-path spectrometer; then a measurement mode is selected for measurement; and finally, spectral polarization data of each wave band acquired by the double-path spectrometer and a division-of-focal plane polarization camera is transmitted to the upper computer through a data line, original spectral light intensity data is calculated according to a measurement principle, and finally a degree of polarization and an azimuth angle of polarization are obtained.

Abstract: Disclosed is a simulation device for electron-excited atmospheric radiation. An electron gun cavity is connected with a front end of a gas cavity. An electron gun is used for emitting electrons and injecting the electrons into the gas cavity. The electrons collide with gas molecules in the gas cavity to ionize and excite the gas molecules. According to the miniaturized simulation device for electron-excited atmospheric radiation, the device can realize an ionization excitation experiment of high-energy electrons on neutral gas and generate a series of optical radiation phenomena in special scenes. In addition, with the aid of optical observation equipment, optical radiation signals of ionized neutral gas can be obtained, so that radiation laws under different incident electron energies, different radiation intensities and different atmospheric components can be further obtained.
