Paper Abstract

Sun is used as light source for spectrum analysis of atmosphere material with sunlight through atmosphere. The stronger sunlight enters the detector, the more accuracy can be achieved. However, due to the inhomogeneity of the atmosphere, the gray image of sun is not only irregular, even the interference of clouds will divide sun into different parts. Thus, when the light intensity, shape and location of sun in the image keep changing, it is critical for obtaining and following the position of the strongest sunlight accurately. In the paper, a novel method of sun scene simulation for observation of the sun through the atmosphere is presented. The method based on the active optical control system, is used in sun scene simulation with the variation of light intensity, shape and position. The method has a simple theory and is easy to be realized. This simulation system composing with computer, projection devices, micro deformable mirror and the optical lens group can be used for simulating optical properties of atmosphere with different density, humidity, and air flow rate, for ensuring the accuracy and real-time sun scene simulation.
