摘要:
Provided is a projection apparatus that can enhance the efficiency of utilization of RGB laser lights, eliminate positional displacement in projection point caused by spaced-apart fiber cores emitting the laser lights, and detect additional information while projecting an image with the laser lights. The projection apparatus includes a laser light source emitting infrared and RGB laser lights, a fixing device fixing end portions of an infrared-light fiber and colored-light fibers used to transmit the infrared and RGB laser lights, a scanning unit projecting an image on a projection surface by scanning the projection surface with the RGB laser lights emitted from the end portions of the colored-light fibers, a detection unit detecting reflection of the infrared laser light emitted from the end portion of the infrared-light fiber, and a control unit controlling emission of the RGB laser lights from the light source, based on information detected by the detection unit.
