Abstract

Adaptive X-ray optics offer significant potential for new optical systems. An analysis and design tool for the optomechanical design of adaptive X-ray optics is presented. The key issues addressed are: 1) The processing of finite element nodal displacements for optical surface characterization is illustrated. 2) The fitting of Fourier-Legendre polynomials to the radial sag or surface normal displacements of near cylindrical optics is presented. 3) The use of 2D Legendre polynomials are presented as an alternative representation of mechanical displacements. 4) The analysis of adaptive X-ray optics requires the solution of actuator strokes required to minimize surface RMS. Issues include stroke limits and surface slope error minimization. 5) The number and placement of actuators can be optimized by using an embedded genetic selection algorithm. 6) The mirror structure and mounts may be optimized to minimize the adaptively corrected surface error while still satisfying all structural requirements. 7) The implementation of a Monte Carlo technique to predict the impact of random factors in the system such as actuator resolution or mount strain forces.
