An improved tomographic-image reconstruction method is proposed that u
ses a hybrid genetic algorithm (GA) that hybridizes a conventional GA
and a concurrent simplex method. For the purposes of discussion, an ax
isymmetric phantom density field is used with an interferometric optic
al projection. Tomographic-image reconstruction using the hybrid GA no
t only improves the convergence over the pure GA but also significantl
y reduces the computation time. (C) 1997 Optical Society of America.
