Research For The Sun Simulator For Weather Sonde Experiment

The sun simulator, which simulates the property of solar radiation on the ground, is a kind of equipment used for test and measurement. The main role is to provide solar radiation source, which is the true distribution of the solar spectrum, stable, uniform, and the irradiation intensity can be set up and control. The solar simulator plays a very important role in many fields, such as utilization of solar energy, examination and calibration of the device of satellite state, remote sensing technology, material measurement, and so on.In this article, the internal and international research status and development on solar simulator is summarized. It advanced the overall design project of the sun simulator for weather sonde experiment, the structure of the optical system and the operating principle of sun simulator. It used a coaxial transmission-type optical structure design project. According to the optical system of the sun simulator, it made optimization design. In order to obtain higher utilization of condenser effect, the condensing system used ellipsoid condenser; to meet the requirements of irradiation uniformity of the sun simulator, the optical system applied optical integrator and increased the number of optical channel. The article also introduced the calculation methods about irradiance in irradiation surface, and made a detailed analysis of the effects of the irradiation uniformity of the sun simulator from the optical integrator. Finally, we verified the design method of the sun simulator through theoretical analysis and testing irradiance, irradiation uniformity, irradiation stability and other technical indicators of the solar simulator.
