This invention relates to the field of aiming device technology and provides a combined aiming
system usable day and night, including an
infrared imaging component, an optical
waveguide imaging component, and a visible light imaging component. The
infrared imaging component is used to collect
infrared light signals from targets within the
field of view and convert the infrared light signals into infrared light images. The optical
waveguide component includes an optical
waveguide lens, and the visible light imaging component includes an optical aiming
system. The optical waveguide lens is positioned on the object side of the optical aiming
system. During the day or when there is sufficient visible light, the visible light imaging component generates a visible light image of appropriate brightness for the target within its
field of view. The shooter can quickly find the target using this sufficiently bright visible light image and thus complete the aiming. At night or when visible light is weak, the infrared light image is displayed on the optical waveguide lens, and the shooter aims at the infrared light image displayed on the optical waveguide lens using the
aiming point provided by the optical aiming system.
