Abstract

A dynamic programming algorithm based on the principle of optimality was developed by Bellman as a method for a multi-stage decision process in the 1950's. We have made a wide frequency change using a step frequency radar and have achived 3-dimensional laser microvision with a very high-resolution limit; the dynamic programming algorithm was employed as a signal processing method. With this 3D laser microvision, we can see through fine structures three-dimensionally to detect faults in them. The resolution limits of usual methods for this purpose are of the order of 10 μm or wider than about 10μm; a resolution limit narrower than 1μm is needed. Based on the principle of the dynamic programming algorithm we derive the resolution limit of 10^<-2>μm and show some excellent characteristics in comparison with the numerically-calculated results using the MUSIC method.
