Abstract
A light outputting apparatus includes a light source that outputs a first light flux, a collimator that parallelizes the first light flux, a light separator that separates the first light flux into a first partial light flux and a second partial light flux, a first light flux width expander, and a second light flux width expander. The light separator causes the first partial light flux to exit in a first direction and the second partial light flux to exit in a second direction. When a first plane is assumed to be a plane containing the first direction and the second direction, the first light flux width expander expands a width of the first partial light flux in a direction along the first plane, and the second light flux width expander expands a width of the second partial light flux in a direction along the first plane.
