A design method of the optical system of the sun simulator for weather sonde experiment was presented: in the past the solar simulator was mainly used for the simulative test of the aircraft in the space environment, the requirements of spectral distribution and irradiation uniformity were relatively low. The developed solar simulator which was used for the performance test of the solar radiation measuring instrument, requiring its spectral distribution was matched with the class A of the AM1.5 solar spectrum in the 0.4-1.1 μm band, irradiation uniformity was ±1% and stability was ±1%/h, actually it was a high-precision and small-sized solar simulator. The system used a design project of coaxial transmission-type and collimating optical system, and we made optimization design at the whole optical system. Through theoretical calculation and practical measurement, spectrum is basically near the AM1.5 solar spectrum and the irradiation uniformity is also less than ±1%, the results meet the design requirements.

According to the whole machine experiment needs of spin scanning earth sensor of Fengyun-2 satellite, a new portable binocular earth sensor was proposed. The composition, general structure and working principle of the simulator system were introduced, and the key technology was discussed. The calculation process of the earth chord width and radiant brightness, and the design process of thermal earth and optical modulator were described as well. The test result indicates that the temperature control precision reaches 0.10°C and the modulation frequency control precision reaches 0.1 Hz, the output signal of the earth simulator that sensor detected is basically anastomosis of its outer space working state waveform.
