Abstract:
1. A light source device comprising: a first light source section adapted to emit a first light beam; a first optical element provided with a first entrance surface to which the first light beam being emitted from the first light source section is adapted to be input, the first optical element being adapted to transmit the first light beam being input to the first entrance surface; and a second optical element provided with a second entrance surface to which the first light beam being transmitted through the first optical element is adapted to be input, the second optical element being adapted to transmit the first light beam being input to the second entrance surface, wherein the first entrance surface is tilted with respect to a principal ray of the first light beam being input to the first entrance surface, such that the first entrance surface is rotated about a primary axis that is perpendicular to the principal ray of the first light beam being input to the first entrance surface, and the second entrance surface is tilted with respect to the principal ray of the first light beam being input to the second entrance surface, such that the second entrance surface is rotated about a secondary axis that is perpendicular to the primary axis.
