Abstract: One or more excitation energy sources emit light in an excitation spectrum and direct the emitted light as an excitation beam to the emitting surface of a wavelength conversion element directly or via reflection. Distinct areas of the emitting surface are coated with one or more distinct fluorescent phosphors. The phosphor-coated areas receive the excitation beam and generate a sequence of fluoresced light beams at a light output, each fluoresced beam of a narrow spectrum determined by the type of phosphor and the excitation spectrum. The fluoresced beams travel parallel to an emitting axis at a non-zero angle to axes associated with the excitation beams.

CPC classification number: H04N9/3105 , H04N9/315
Abstract: A multi-DMD projection system uses an extended X-cube color splitting/recombining prism to implement splitting and recombining functions at different sections of the cube. Light directed from a white light source is split into red, green and blue components in a lower section of the cube. The components are directed to respective first, second and third DMDs for separate modulations and reentered into the X-cube prism by TIR prism for recombining at an upper section of the cube.

Abstract: Described are handheld devices with combined image capture and image projection functions. One embodiment includes modulating and capturing a light beam along the same optic path. In another embodiment, the optical components are operable to switch between projection and capture modes. In yet another embodiment, the optical components may be formed on the same semiconductor substrate thereby increasing functionality.
