Abstract

This paper will discuss how mechanical and optical analysis software can be used together to optimize an opto-mechanical structure subjected to vibrational loading. Mechanical analysis software output is post processed into Zernike polynomial coefficients and rigid body motions for analysis with optical modeling software. Structural modifications can then be implemented to improve optical performance. A Cassegrain telescope, which can be utilized for laser radar applications, will be used to demonstrate this optimization. Two FEA solution methods are compared. Based on the deformation results of the FEA, Zernike polynomials and rigid body motions are generated and applied to the optical surfaces in CODE V^®. The effect of these deformations on wavefront can then be computed and compared to a required performance.
