Light divider

A light divider comprising:

• a one-dimensional light divider that one dimensionally divides light incident thereon and outputs a plurality of light fluxes;
• and
• a two-dimensional light divider that two-dimensionally divides the plurality of light fluxes outputted from the one-dimensional light divider,
• wherein the one-dimensional light divider includes
• a first light guide having a first surface and a second surface that reflect light incident on the first light guide and causing the light to propagate through a portion between the first surface and the second surface,
• a first light dividing layer that is provided on the second surface and divides the light having propagated through the first light guide into reflected light and transmitted light,
• a first member that reflects the light that the first light dividing layer has transmitted, and
• a second member that reflects the light that the first light dividing layer has reflected,
• the light reflected off the first member exits through the first surface,
• the two-dimensional light divider includes
• a second light guide having a third surface and a fourth surface that reflect light incident on the second light guide and causing the light to propagate through a portion between the third surface and the fourth surface,
• a second light dividing layer that is provided on the fourth surface and divides the light having propagated through the second light guide into reflected light and transmitted light,
• a third member that reflects the light that the second light dividing layer has transmitted, and
• a fourth member that reflects the light that the second light dividing layer has reflected, and
• the light reflected off the third member exits through the third surface.
