【Abstract】 The Structural design, operating principle, accuracy analysis and developingresult of pinhole camera used for the target chamber of "Shenguang Ⅱ" laser fusion areintroduced. The alignment of the target is carried out by means of optical CCD-TVimaging electric alignment technique used in the pinhole camera. The repetition accuracyin X direction is 5um and in Y direction is 7um.更多还原
