ABSTRACT:
First and second polarized light beam splitters13, 14split non-polarized light L into p polarized light P and s polarized light S1and allow the p polarized light P to transmit in the same direction as that of the non-polarized light L, reflecting the s polarized light S1. A light emitting apparatus1emits one the s polarized light and the p polarized light that are split by the first and second polarized light beam splitters13, 14as first vertical polarized light having a vibration plane in an electric field substantially perpendicular to the ground and converts the other of the p polarized light and the s polarized light by first and second½wave plates5, 6for converting a vibration plane in an electric field as second vertical polarized light having a vibration plane in an electric field substantially perpendicular to the ground for emission.
