In order to reduce the size and weight of the gimbal in a traditional stable platform and correct the disadvantage in size of the payload  the paper first improves the gimbal which is an important component of a stable photoelectric platform  that also is an important factor in affecting the size and weight of a stability platform. In this paper  a closed-form solution of 3-DOF manipulator is designed according mechanical arm design principles. This manipulator is formed by a three joint axes whose extended line is intersected at one point. A standard orthogonal coordinate system is set up for each rod in the manipulator. And then  rotation transformation matrix expression is obtained. At last in this paper  the manipulator arm-shaped method for solving solutions is description  and also  each parameter of the gimbal is calculated when the photoelectric detection devices at bottom reach the expected position. Test results show that the photoelectric stability platform with gimbal we designed is smaller  lighter and simpler than that traditional. Also  the packaging and size of the photoelectric will not be affected with this open structure. 2010 IEEE.
