The optical parameters of optical components for a space optical remote sensor are usually determined by the experience of a designer. By establishing a full damping dynamic analysis model for a space optical remote sensor, the expressions of dynamic response of optical components are obtained. In view of the actual engineering condition, the dynamic response of the optical components is analyzed numerically through MATLAB programming when a damp ratio is 0.03 and a mass ratio is 0.2. The result shows that to keep the dynamic response of an optical component as low as possible, a reasonable frequency should be selected rather than increasing the dynamic response of the optical component subassembly blindly.
