1. A beam shaping method employing full-image transfer for planar light sources, comprising the following steps:
(1) using multiple first lenses to respectively magnify and image beams emitted by multiple planar light sources, so as to obtain magnified full images of the multiple planar light sources; and
(2) stitching the magnified full images of the multiple planar light sources at a primary imaging position, so as to obtain a seamless light source; wherein along any section of a primary optical axis, the distance u between each of the planar light sources and the first lens and the distance v between the first lens and the primary imaging position satisfy the following formulas simultaneously:, 1
