Abstract
A two dimensional image forming device includes: a laser light source (1) which is a coherent light source; a prism array (2) that changes the traveling direction of a beam exiting from the laser light source (1); a driving portion (3) that rotates the prism array (2); a rod integrator (4) that guides the exiting beam deflected on the prism array (2) while allowing the beam to undergo internal reflection; a projection optical system (5) that projects the exiting end face of the rod, integrator (4) onto a two dimensional spatial light modulation element (7); and a projection lens (8) that projects light exiting from the two dimensional spatial light modulation element (7) onto a specific plane within a space.

1-12. (canceled)
A two dimensional image forming device, characterized by comprising:
- at least one laser light source;
- a beam deflection portion for changing a traveling direction of a light beam emitted from the laser light source;
- a driving portion for driving the beam deflection portion to change timewise a traveling direction of the light beam exiting from the beam deflection portion;
- a rod integrator that guides the light beam deflected by the beam deflection portion to an exiting end thereof while allowing the light beam to undergo internal reflection;
- a first projection optical system that projects the light beam exiting from the rod integrator;
- a two dimensional spatial light modulation element that modulates the light beam exiting from the first projection optical system;
- and
- a second projection optical system that projects light exiting from the two dimensional spatial light modulation element onto a specific plane.
