Outline of Final Research Achievements

We have developed a motor-less small, fast and low power laser scanner by using a DMD (Digital Micro mirror Device) and a special formed mirror. We also fabricated an estimation system for it, and did the estimations.
Several special mirror types were come up with, and basic functions of each have been confirmed. Because of the hardness of constructing the experimental system and limits caused by using a commercial DMD, however, we could not achieve the expected resolutions. Therefore, we have proposed new types of special formed mirrors and done preparative simulations.
