Abstract
An optical array includes one or more optical elements each including an incident surface at which light is incident into the optical element, a first reflection surface at which the light passing through the incident surface is reflected, a second reflection surface at which the light reflected by the first reflection surface is reflected again, an emission surface at which the light from the second reflection surface exits the optical element, and a refractive surface at which light that passes through the first reflection surface is refracted away from the emission surface.
