A lightweight holographic sighting system is provided that is designed to minimize optical aberrations common with earlier holographic sighting systems. The system has a modular construction that is more economic and conducive to high volume production, in terms of complexity of required fixturing and availability of materials, than earlier systems. The system is lighter and more compact, while providing a larger field of view than existing systems, and can be used on small hand guns, standard size firearms, bows, telescopes, and other devices without adding significant weight or space constraints. The system utilizes an upper housing assembly containing a high efficiency holographic optical element, an anti-reflective glass viewing window, and a red diode laser light source driven by a high efficiency microcontroller circuit designed for increased battery life, and a lower housing assembly containing two dielectric folding mirrors, an on-axis collimating lens, and a high efficiency achromatizing holographic optical element.

An electro-active lens provides simultaneous focusing at two different optical powers. It does this with a stack of electro-active lens elements aligned along the same optical axis that each focus light in different polarization states (e.g., horizontal and vertical polarization states). If a first and second electro-active lens elements have different optical powers, light in a first polarization state can be focused to one optical power and light in a second polarization state can be focused to a different optical power simultaneously. The electro-active lens can be switched between different single and multiple optical powers. People with presbyopia may use the electro-active lens mounted in eyewear in place of conventional bifocal glasses. The electro-active lens may also be used in a scope to improve target aiming.

Certain aspects of a novel weapon sight system combine a direct view, a visible light video view, and an infrared (IR) video view mode. Each of the view modes may be viewed individually or simultaneously with one or more of the other view modes through a single viewing aperture. Further, the one or more view-modes may be provided while providing a bore-sighted reticle superimposed on the selected view. Further, the reticle may be powered separately from the video view electronics enabling use of the reticle regardless of the power status video view electronics.

The present invention relates to a split-type fusion sight, comprising a sight main body. An aiming assembly connecting base is arranged at the top of the main body; the aiming assembly connecting base comprises an engagement groove located on the front side, and an engagement base located on the rear side; an engagement block is arranged in the middle of the engagement groove, and a wire arranging base is arranged on the right side of the engagement base; the aiming assembly connecting base is further provided with connecting screw holes. The split-type fusion sight can fuse the low-light-level night vision or thermal imaging lens imaging with human eye observation of a target to assist in observing or determining the target, and then determines the aiming target by means of an aiming light point, thereby performing accurate shooting. In addition, the low-light-level night vision or thermal imaging lens imaging module is arranged above the sight main body, and is fixedly connected by means of the aiming assembly connecting base and connecting screws. It is convenient to replace the low-light-level night vision module or thermal imaging module, the sight main body does not need to be disassembled, and disassembly and replacement are more convenient.
