A light source unit includes a display device configured to display an image, and an imaging optical system including an input element and an output element; light emitted from the display device is incident on the input element; light traveling via the input element is incident on the output element; and light emitted from the output element forms a first image corresponding to the image. The imaging optical system is substantially telecentric at the first image side. The light emitted from the display device has a substantially Lambertian light distribution.
