This paper focused on the optimal design of CGH, minimizing the line density of CGH, in testing offaxis aspheric mirror with large aperture, offaxis amount and asphericity. The analytics formula of the transferred aspheric is used for deriving the phase function of CGH by geometric computing. And the precision of optical path difference(OPD) is proved reaching nanometer level for aspheric mirror with large asphericity by zemax. The defocus and tiltcarrier amount are two parameters to be optimized for filtering the unwanted orders brought out by CGHs. A merit function consists of the line densities at lower and upper boundaries of CGH to describe the etching difficulty of CGH is proposed. The propagation progress is analyzed while the reflection is amended by considering the saggital height of the reflection point. The separated distance of the given (m,n) orders ray is proved reaching micron degree. The filtering condition is expressed as an inequalities system. The gradient descent method with Karush Kuhn Tucker condition is used for optimal solution of the constrained optimization problem. Finally, design example is presented and the parameter optimization for testing offaxis aspheric mirrors is proved to have a high precision, which providing extensive applicability possibility in designing freeform testing system.OPTICAL DESIGN AND TESTING VIIIOptimal parameter solution for optical design of testing largeaperture offaxis aspheric mirror with computergenerated holograms会议论文EnglishLi, Xuyu; Wei, Chaoyang; Xu, Wendong43609 WOS:000452639600048
