Freeform surface adaptive interferometry assisted with simulated annealing-hill climbing algorithm

The freeform surface adaptive interferometer (FSAI) recently has been employed to realize the unknown metrology. A near null interferogram should be acquired from initial with undistinguished fringes even dark areas. direct optimization object in FSAI is just rather than focusing intensity characterization traditional wavefront-sensorless (WFS) systems. simulated annealing-hill climbing (SA-HC) mixed algorithm FSAI, which much better convergence stochastic parallel gradient descent (SPGD) algorithm, almost as genetic (GA). At same time, it faster GA and thus applicable test of volume-produced optical shop. Simulations experiments validating feasibility are presented.
