Abstract:
1. An optical scanning projection module, comprising: a scanning light component, comprising a plurality of sub light sources and at least one light-splitting element, wherein sub light beams of the sub light sources are converged to form a main light beam, and one of the sub light beams travels to the at least one light-splitting element to form a partial transmissive light and a partial reflected light; a main light reflective element, for reflecting the main light beam; a scanning element, wherein the main light beam, which travels from the main light reflective element, is reflected by the scanning element with a scanning manner to be a projection light, and one of the partial transmissive light and the partial reflected light is reflected by the scanning element with the scanning manner to be an inspection light; and a photosensitive element, for receiving the inspection light to output a sensing signal; wherein the optical scanning projection module controls the scanning light component in accordance with the sensing signal.
