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.

In order to ascertain the effects of main errors of alt-alt photoelectric telescope on measurement accuracy  orientation error is analyzed.For analyzing optical  mechanical and electrical errors from measured target to telescope picture  we construct 7 coordinates such as:the earth's core coordinate  alt-alt coordinate  etc.  carry through 21 times coordinate transformation  form measuring equation with 26 variables. and we utilize Monte Carlo method to calculate the orientation error  analyze the effects of errors upon pointing. The result indicates that the measuring error standard deviation of alt-alt telescope is minimum value about 10? at the zenith zone. and the deviation increases with the rotation angles of longitude and latitude axes. The model and the method not only can analyze and synthesize the main errors  but also provide a reference to the whole design. 2009 SPIE.

This paper proposes that the inter-layer separation distance (ISD) and the unit cell aligning error (UAE) are used as main variables to study the transmission performance attenuation of the double layer FSS configuration. The numerical analysis model for ISD and UAE was established and also was used to simulate the cross loop slot cell FSS transmission performance by the finite element and periodic moment method program. The double layer cross loop aperture FSS configuration designed was used as the numerical model. As a result of the numerical analysis  it is shown that both ISD and UAE produce insertion transmission loss (ITL) and insertion phase distortion (IPD) directly. Furthermore  ISD results in much loss of the amplitude of the transmitted signal for the FSS than UAE. It is significant for the designer for the multiplayer FSS to assign the fabricated error of the FSS dielectric layers. The UAE introduces the insertion phase variation badly.
