Micro-optics is a new branch of optics.There is considerable interest in micro-optics system made by micro-fabrication techniques to produce arrays of miniature optical componentsfor the control of light
recently.This paper reviews the present status and future potentialof research and development for micro-optics
in which includes binary optics
gradient indexoptics and fibre matrix optics
etc. Some application examples are presented so as to showpromising prospect in many feilds.
