Abstract
This research proposed a new method HTGA (Hybrid Taguchi Genetic Algorithm) for extended optimization of 350X zoom optics with DOE (Diffractive Optical Element) in order to eliminate chromatic aberration efficiently. Thanks to negative Abbe number of DOE, the optimal eliminating chromatic aberration could optimized and minimized with DOE coefficient and glass material. Following the advanced technology applied to micro lens and etching process, precisely-made micro DOE element now is possible to be manufactured in a large number. The steady Taguchi method incorporated with the genetic algorithm (GA), called hybrid Taguchi-genetic algorithm (HTGA), proposed in this research, have reached success in determining the best position for DOE plane and conclusively eliminate the chromatic aberration of 350 Zoom optics with DOE element and various glass materials.
