Abstract:
1. A beam shaping module receiving a polarized beam from a light source, the beam shaping module comprising: a beam splitter, which is a polarized beam splitter capable of splitting the polarized beam into a first beam and a second beam, wherein polarization directions of the first beam and the second beam are perpendicular to each other, and said beam splitter is capable of introducing the first beam and the second beam to a reflecting unit comprising a first reflector and a second reflector to reflect the first beam and second beam to a beam combiner, and the first reflector and the second reflector are disposed in parallel; and a beam combiner, the beam combiner comprises four cubic glasses, two of which are polarized-beam-splitting cubic glasses disposed diagonally and another two are general optical cubic glasses disposed diagonally, said four cubic glasses are capable of preventing the beams from being deviated, and said two polarized-beam-splitting cubic glass function the same as the polarized beam splitter does, said beam combiner is capable of shaping and combining the first beam and the second beam and reversing the energy distribution pattern of one of the first beam and the second beam.
