Abstract

Numerical analysis and simulation of a technique for automatic alignment of a three-mirror off-axis telescope were carried out using a method of reverse optimization and end-to-end measurements. The techniques uses Hartmann measurements made at multiple field points and multiple focus planes. The reverse optimization method uses the Hartmann data as target values in a standard lens design program and damped least squares optimization to determine the state of misalignment of the system. Once the state of misalignment is determined a single step correction of all misalignments is possible in principle. Our results show that multiple measuring planes make possible a larger capture range, faster convergence, and larger measurement tolerances than does a single measurement plane.
