A beam shaping method and device employing full-image transfer for planar light sources. The method comprises: 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 seamlessly stitching together the magnified full images of the multiple planar light sources at a primary imaging position, so as to obtain a seamless light source at the primary imaging position. The beam shaping method for the planar light sources achieves the elimination of gaps between the light sources with almost no loss of optical power by means of full-image transfer and seamless stitching, thereby improving the beam quality of the light sources as a whole. This kind of optical shaping method is suitable for shaping and processing planar light sources such as VCSEL and LED.
