1. An optical system comprising:
a prism having an incident surface, an exit surface, and one or more reflecting surfaces;
a first scanning element configured to scan in a first direction a light that enters and reflect the light in a direction of the incident surface of the prism; and
a second scanning element configured to scan in a second direction the light that exits from the exit surface of the prism, the second direction being orthogonal to the first direction, wherein
the incident surface of the prism, incident on the light scanned by the first scanning element, has a convex shape with respect to the first scanning element, and
a two-dimensional image is formed from the light incident on the first scanning element by scanning in the first direction by the first scanning element and scanning in the second direction by the second scanning element.
