| Introduction | A converting device converts an unpolarized incident light into a polarized emitting light. The converting device includes a polarizing or polarization beam splitter, a converting module, and a retroreflector. The polarizing or polarization beam splitter splits the unpolarized incident light into a first polarization wave and a second polarization wave, the polarizing or polarization beam splitter reflecting the first polarization wave and allowing the second polarization passing through thereon. The converting module receives the second polarization wave and converting the polarization direction of the second polarization wave to match or approximate a polarization direction of the first polarization wave, and guiding the converted second polarization wave to an output direction. The retroreflector is coupled to the polarizing or polarization beam splitter and reflects the first polarization wave to the output direction. Finally, the reflected first polarization wave and the converted second are combined into the polarized emitting light. |
