Patent ID: 7646518

Claim:
A two dimensional image forming device, comprising: at least one laser light source; a beam deflection portion that changes a traveling direction of a light beam emitted from said laser light source; a driving portion for driving said beam deflection portion to change timewise a traveling direction of the light beam exiting from said beam deflection portion; a rod integrator that guides the light beam deflected by said 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 said rod integrator; a two dimensional spatial light modulation element that modulates the light beam exiting from said first projection optical system; and a second projection optical system that projects light exiting from said two dimensional spatial light modulation element onto a specific plane, wherein said beam deflection portion includes a lenticular lens having optical axes disposed to be substantially orthogonal to each other and deflecting the light beam exiting from said beam deflection portion in a horizontal direction and a vertical direction.
