The present invention relates to a deployable optical structure for space with a high-precision focus mechanism. The structure comprising a tube including a first tube which has a first mirror at one surface and a spiral grooved cam formed in a longitudinal direction, a second tube which is coupled to the inside of the first tube and has a guide hole on a straight line, and a third tube which is coupled to the inside of the second tube and has a fixing pin capable of moving along the grooved cam and the guide hole; a transfer means installed on the outer surface of the first tube and transferring the third tube to protrude along the grooved cam of the first tube; and a deployment means transferring a second mirror installed inside the third tube. Since the separated second tube and third tube are stored in the first tube, the structure can be easily mounted on a small satellite. Further, a high-resolution image can be obtained by extending the second tube by a first deployment means. |
