提出一种气象探空仪试验用太阳模拟器光学系统的设计方法:以往的太阳模拟器主要用于航天器空间环境模拟试验,对光谱分布和辐照均匀性要求相对较低。该文研制的用于太阳辐射测量仪器性能检测的太阳模拟器,要求其光谱分布在0.4～1.1μm波段范围内与A级AM1.5太阳光谱相匹配;辐照均匀性为±1%;辐照稳定性为±1%/h;属高精度小型太阳模拟器。采用一种同轴透射式准直光学系统的设计方案,并对整个光学系统进行优化设计,经理论计算与实际测量,光谱基本在AM1.5附近,辐照均匀性也小于±1%,结果满足设计要求。
A design method of the solar simulator optical system for the test of the weather oximeter is proposed. The former solar simulator is mainly used for spacecraft space environment simulation test, and has relatively low requirements on spectral distribution and radiation uniformity. The solar simulator developed for the performance measurement of solar radiation measuring instruments requires that its spectral distribution should match the A-class AM1.5 solar spectrum in the wavelength range of 0.4-1.1μm; the uniformity of irradiation is ± 1%; the radiation According to the stability of ± 1% / h; a high-precision small solar simulator. A coaxial transmissive collimating optical system was designed and optimized for the entire optical system. Theoretical calculation and actual measurement showed that the spectrum was basically near AM1.5 and the radiation uniformity was less than ± 1%. The result Meet the design requirements.
