Focal Surface Projection: Extending Projector Depth of Field Using a Phase-only Spatial Light Modulator

  • We proposed a focal surface projection to extend a depth-of-field of a projector.

    We present a focal surface projection to solve the narrow depth-of-field problem in projection mapping applications. We apply a phase-only spatial light modulator to realize nonuniform focusing distances, whereby the projected contents appear focused on a surface with considerable depth variations. The feasibility of the proposed technique was validated through a physical experiment.
