The utility model provides an extra-large-view-field and multi-target scenery simulation system which comprises a light source system, a target system, a collimation system, a rotary beam splitting system and a control system, wherein the light source system provides a uniform face light source; the uniform face light source forms a target beam through the target system; and the target beam passes through the collimation system, then is divided into more than two parallel beams by the rotary beam splitting system, and enters a to-be-tested imaging system. The system can solve the problems that the cost is high due to multiple collimator tubes, and a scenery simulation view field is too small caused by a movement mechanism at a focal plane; the system is concise in structure, can achieve multi-target and large-view-field scenery simulation, and saves the acquisition cost of testing equipment greatly; under the condition that the collimation system is not increased, double-target scenery simulation is obtained ingeniously; through expansion of a beam splitter prism, simulation of more targets can be achieved; and the system is an initiate in China. |
