Abstract: |
A light storage-reshaping structure of blue laser beam is prepared for forming said structure by 2n numbers of reshaping prisms, using triangle prism as each said prism, setting light incoming angle of 2i-1 number reshaping prism to be equal to that of 2i number reshaping prism, setting outgoing light axle of 2i-1 number reshaping prism to be vertical to its outgoing surface and outgoing light axle of 2i number reshaping prism to be vertical to its outgoing surface, using natural number as n and using natural number 1-n as i. |
