Method and system for manufacturing hologram and holographic lens combined element

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

technical field [0001] The invention belongs to the field of manufacturing holographic elements, and in particular relates to a manufacturing method and a manufacturing system of a hologram and a holographic composite element. Background technique [0002] The research on holography has entered a new stage since the appearance of the world's first laser in the 1860s, and now it has expanded to holographic interferometry, holographic storage, holographic optical components, holographic microscopy, display holography, digital holography and other fields.

AI Technical Summary

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 parallel light to see the diffraction image during reproduction. The holographic aiming optical system made of such conventional components is relatively complicated. Reflector, at the same time, in order to compensate the wavelength change due to temperature and humidity, it is necessary to add a holographic grating; or use a holographic lens to obtain parallel light to reproduce the holographic dry plate
