description The utility model provides a holographic optical path which comprises a laser diode, a holographic optical grating and a holographic combination element, wherein the holographic optical grating is used for deflecting laser emitted by the laser diode, the holographic combination element is used for aligning and filtering the diverging light and displaying the holographic differential picture; the holographic combination element is a combined holographic element with property of lens and property of imaging hologram and is formed by a light-sensing glue film and two piece of glasses glued on both sides of the light-sensing glue film. The holographic optical path has the characteristics of few elements, multiple styles of optical path and short length, so that the product using the optical path is compact and variable in structure, and moreover, the holographic optical path overcomes the shortcomings of long length, multiple elements, complex optical path and single style of optical path.
