%X To compensate the defocusing of a dual-band aerial camera in a complicated environment, a focusing mechanism is designed. The mechanism compensates the defocusing by using a worm-gear and an eccentric cam to convert the rotation of the focusing cam into the straight line motion of a mirror. It has the advantages of high transmission ratio, stable operation, compact structure, antivibration, self-locking and modularization. The calculation result shows that its focusing mirror has a displacement precision of 0.0026mm and the simulation result shows that the method is feasible.
