Demarcation Technology on the Earths Field Angle of Collimating Infrared Earth Simulator

摘要：

The size of Earths field angle is one of the most important parameters of Earth simulator. At present, this parameter can only be calculated by the way of optical calculation, and can not be tested exactly. Infrared detecting and optical modulation technique are introduced in the paper to demarcate the Earths field angle. The field angle demarcating systems elements, general structure and measuring principle are all analyzed detailed in the paper. The small field infrared detector, the key element for demarcating field angle is discussed and analyzed theoretically and experimentally, and it can be seen from the experimental results that the Earths field size and shape is 0.41°×0.49° and ellipse respectively.
