  • Patent number: 10928640
    Abstract: An optical system for assisting image positioning. The system comprises a light source (1), and further comprises a dot pattern or an interface beam-splitting pattern which is arranged on a light-emergent light path of the light source (1) and generates an interface beam-splitting projection light ray for indicating a text or an image after being projected by emergent light of the light source (1). By means of a combination of a light source (1) and a dot pattern or an interface beam-splitting pattern, a word line, a cross line, or the other patterns which can generate a beam-splitting interface can be projected. Furthermore, by virtue of a DOE moulding lens, of which an emergent face is a spherical face or an aspherical face, a specific linear light beam or the other patterns which can generate the beam-splitting interface are generated.
