A ground based airglow imager interferometer (GBAII) has made in our group to detect the upper atmospheric temperature and wind velocity at terrestrial altitude 90-100 km. GBAII’s sources are the airglow of O (1S) 557.7 nm at altitude of 97km and O2 (0-1) 867.7nm at altitude of 94 km. a uniform value of the atmospheric transmissivity was used in the forward and inversion process of GBAII, which was led to GBAII a lower wind measurement accuracy. The atmospheric transmissivity of O2 (0-1) airglow is calculated and simulated in this paper. Based on the analysis and calculation of the high level atmospheric absorption, scattering attenuation, scattering ratio, acquire transmittance and the attenuation ratio of CO2 and water vapor are obtained by adding the methods of weighted mean, number density of molecules, different height modified segments, the different correction factors vs. different atmospheric heights etc. By MATLAB programme, the atmosphere scattering ratio is obtained to be 1.876×10-3, CO2 transmittance to be 0 and water vapor to be 0.1888, respectively. The total atmospheric transmittance of O2 (0-1) airglow is 0.4663.
Based on the laser writing device developed by our group before, wiping the glow is necessary as a function added on the machine. This article is a theoretical and experimental study of glow wiping start from luminescence theory and infrared ray. The trap depths of ZnS: Cu and SrAl2O4:Eu2+, Dy3+ are figured out according to the TSL(thermos stimulated luminescent ) dynamics, then the accurate IR wavelength to release the trapped electrons in proper depth. We select every single wavelength of energy 1nm by 1nm from near IR and deliver it by crystal fiber. The glow fading curves of ZnS: Cu and SrAl2O4:Eu2+, Dy3+ are figured under IR. The TSL spectrum of ZnS: Cu and SrAl2O4:Eu2+, Dy3+are measured with a thermal luminescence meter. The experiment result of glow wiping has proved the theory. This paper provide a pioneer experiment and theoretical base for further study of IR quenching wavelength about more variety of LLP material.
