Optical scanning type projector

摘要: PROBLEM TO BE SOLVED: To provide an optical scanning type projector which is uninfluenced by operating environment and, despite compact, displays a wide angle image at high resolution and quality even in narrow space. SOLUTION: The includes: light source parts (2R, 2G, 2B) generate plurality of different colors modulated on the basis signal; luminous flux diameter adjustment (3R, 3B, 4R, 4B) include beam expander 15 expands diameters fluxes, substantially equalizes fluxes having generated from parts; color synthesizing (5, 6, 8, 12, 13) synthesize adjusted onto one same axis; part 17 deflects synthesized two-dimensional direction according to free curved face prism 18 has faces 18a 18d non-rotational-symmetry shapes, projects deflected with while enlarging least deflection angle, wherein displayed projected 18.
