摘要 |
A first light source that emits first light of a first wavelength band; an optical path separator that separates the first light into third light and second light whose polarization directions are orthogonal to each other; an optical path separator and combiner that separates the second light into fourth light and fifth light having different wavelength bands from each other; a reflector that reflects the fifth light to a direction of the optical path separator and combiner; and an optical path combiner that combines the third light and the second light are included. |
