Problems solved by technology

[0003] At present, the holographic lenses produced by conventional methods basically only realize the basic functions of light divergence, reduction, and parallel lenses, and do not have the properties of diffractive holographic images; the holographic elements produced by conventional methods only carry To record the information of the object image, the diffraction image needs to be irradiated with par

Embodiment Construction

[0028] The technical core of the present invention is that a combination of a hologram and a holographic lens is produced by interference of a beam of parallel object light and a beam of divergent light. The component simultaneously records the properties of the lens and the image of the object. The holographic lens combination can be The transmissive holographic composite element may also be a reflective holographic composite element.

[0029] figure 1 Shown is a schematic diagram of the optical path for producing a transmission hologram and a holographic composite element. The specific production process is: a laser light source 1 emits a beam of laser light, which is divided into two beams of light after passing through the diaphragm 2 and the beam splitter 3 (that is, a beam of reflected light and a beam of transmitted light) are respectively reflected by the first reflector 4 and the second reflector 6, and the transmitted light reflected by the second reflector 6 becomes...

Abstract

The invention provides a method and system for manufacturing a hologram and holographic lens combined element. The method comprises the steps of: emitting a light beam by a laser light source, splitting the light beam into two light beams through a spectroscope and respectively reflecting the two light beams by two reflectors, enabling one light beam to pass through a beam expanding lens and a pinhole filter to become uniform diverging light and enabling the other light beam to pass through an image imaging system to become parallel light (object light), wherein the diverging light is interfered with the parallel light; recording relevant information on a holofilm, selecting proper exposure time according to the light intensity; and obtaining the hologram and holographic lens combined element after developing. The method is simple and easy to realize; and the manufactured hologram and holographic lens combined element records properties of a lens and an object image, thereby overcoming the defect that the traditional holographic lens has no function of diffracting images of reticles and the like, and laying the foundation for providing a simpler and more efficient holographic collimator light path.

Description
