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.
