An optical supporting structure is studied to improve its structure stiffness and reduce the rotate error to meet the requirement of aviation remote sensor. A formula to calculate fundamental frequency is proposed using Rayleigh-Ritz method  and a method of is analyzed. By means of OPTISTRUCT software  the maximum fundamental frequency is converted to object function  the deformation under the gravity and the mass are assigned to state variable  wall thicknesses of the structure are converted to design variables. The analysis and test results indicate that the fundamental frequency of designed optical supporting structure has been improved 37.2 Hz from 96.9 Hz  which guarantee the reliability of the sweep mechanism  and the rotate error is 4.89  which is satisfied for the rotate accuracy in plunge angle. The method of optimization has a certain instructional significance for the design of supporting structures in aviation remote sensor. 2011 IEEE.
