Abstract
An optical irradiation apparatus includes: a light-emitting device configured to emit a plurality of light beams whose optical axes extend in a substantially identical direction; a collimator part configured to convert the light beams into parallel light beams; and a light condensing part configured to collect the parallel light beams. The light-emitting device includes a super luminescent diode array in which a plurality of waveguides are provided on a substrate. Each of the waveguides has a light-emitting facet including a light emission point from which an associated one of the light beams is emitted. The light emission points are located in a plane. The plane including the light emission points is orthogonal to a direction of an optical axis of the collimator part.
