More Information
Summary:A light source unit includes a surface-emitting laser array including light emitting units; and an apertured member provided on a light path of light beams emitted from the surface-emitting laser array, the apertured member including an aperture. In at least one direction, an intensity distribution of interference patterns caused by the light beams passing through the aperture includes an equal number of crests and troughs.
