Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] This embodiment provides a positioning system for hologram printing, the overall block diagram is as follows figure 1 As shown, the image output by the upper computer PC needs to be output by a spatial light modulator such as an LCD to the equipped optical path and then imaged and recorded on the holographic dry plate. The exposure time is controlled by the mechanical shutter, and the servo motor moves the holographic dry plate to determine the interfere...

Abstract

The invention discloses a positioning system for hologram printing, which relates to the technical field of holographic display. The positioning system comprises a principal computer, a control card,a pulse hand wheel and a servo system. An image output by the principal computer is recorded under interference at a holographic plate. The servo system controls the position of the holographic plate,and determines the position of interference imaging. The servo system consists of a servo amplifier and a servo motor. The principal computer is equipped with the control card, and outputs a pulse through programming to drive the Siping servo motor. The pulse hand wheel manually inputs a pulse to drive the servo motor to move the holographic plate. The positioning system for hologram printing hasthe advantages of stable operation, accurate walking and ideal printing effect, and achieves functions such as automatic exposure in holographic printing, automatic positioning of the holographic plate and automatic image output.

Description

technical field [0001] The invention relates to the technical field of holograms, in particular to a positioning system for hologram printing. Background technique [0002] Holographic laser interference printing belongs to laser interference lithography technology. Interference lithography technology integrates laser, diffraction and interference optics and optical lithography. Development has important significance and broad application prospects. [0003] Existing commercial digital holographic production technologies are usually based on laser lithography, including laser direct writing lithography, laser projection lithography, and laser interference printing. Laser interference printing is one of the more efficient lithography technologies. kind. The production level of existing large-area digital holographic products in China is far behind the international advanced level in terms of size and quality, and it is limited to the use of blue lasers to record transmissio...
