To make optical components have their dynamic response as small as possible and meet the required mass specifications, the mass of a space optical remote sensor should be distributed. By establishing a full damping dynamic analysis model for the space optical remote sensor, the expression for the dynamic response of the optical components is obtained. The dynamic amplification characteristics of different dynamic systems are discussed according to the expression. Then, in view of the actual engineering condition, numerical analysis is made via MATLAB programming and the mass distribution condition under which the response of the optical components can be made as small as possible is discussed. The result shows that the optical components have their dynamic response close to the minimum value for a damp ratio of 0.03, a frequency ratio β of 1.3 and a mass ratio of 0.51. Because the method proposed according to the theoretical formula can interpret the result in the formation of chart, it is reliable and easy to use.
