The UV-A and visible solar irradiance spectrum: inter-comparison of absolutely calibrated, spectrally medium resolution solar irradiance spectra from balloon- and satellite-borne measurements

, 2004
International audienceWithin the framework of the ENVISAT/-SCIAMACHY satellite validation, solar irradiance spectra are absolutely measured at moderate resolution in the UV/visible spectral range (in the UV from 316.7–418 nm and the visible from 400–652 ...

紫外LED散射通信信道特性与传输研究

Guangtongxin yanjiu, 2013
利用modtran大气传输模型对低空信道紫外光传输特性进行分析,研究了近地短距离传输的大气吸收和散射的数学模型。在实验室环境下,系统采用视场角为80°的紫外LED（发光二极管）发射,在传输距离为5～8m的情况下进行了模拟信号的散射传输测试。结果表明:利用一定的有效散射体,收发俯仰角从10°增加到65°时,能有效实现短距离紫外散射传输。散射体浓度过大对紫外光存在强烈的吸收作用,传输距离将减小,单个紫外LED发射功率低,实际通信应用中,可采用阵列LED来提高发射功率,增加传输距离。
