Embodiment 1

[0124] First, a three-dimensional modeling object is designed by using 3D-MAX, and the sequence view of the model object is obtained, and calculation is performed, and a computer-made synthetic color rainbow holographic calculation is obtained.

[0125] The relevant parameters are: the included angle of material parameters is 14.5°, the calculated wavelengths are 632um, 547um and 464um, the number of views is 47, z e =400mm, the slit length is 141mm, the slit width is 3mm, the object size is 20mm×20mm, and the number of pixels on the holographic surface is 35080×35080. It is implemented by MATLAB programming, and it takes 419.76 seconds to calculate using a personal notebook (acer-v3-571G, i5-2450M processor). The holographic stripe output system developed by the laboratory is used to output the calculated synthetic color rainbow hologram on the Tianjin Type III dry plate, and then develop, fix and bleach to obtain a synthetic rainbow hologram that can be actually optically re...

Embodiment 2

[0127] We use a small rotating platform and camera to shoot according to a certain rotation angle to obtain the view sequence of the actual object, and use this method to make a true-color rainbow hologram. The number of views is 41, the slit length is 123mm, the object size is 20mm×24mm, and the pixel point is 35080×42120. The calculation time is 474.9 seconds. Other parameters are the same as above.

[0128] Figure 9 (a)-(c) show three views of the actual object, (d) is a partially enlarged screenshot of the hologram, and (e)-(g) are the optical reconstruction results.

Abstract

The invention relates to a method for making a computer-made synthetic color rainbow hologram. Step 1, 3D object sequence view acquisition; Step 2, parameter setting; Step 3, synthesis of three primary color bands; Step 4, calculation of holographic fringes. The invention is a high-quality and fast method for synthesizing rainbow holograms in true color, which can realize the production of true color synthesizing rainbow holograms on ordinary personal computers.

Description

technical field [0001] The invention relates to a computer-made synthetic color rainbow hologram production method. Background technique [0002] Synthetic holography is a technology that obtains a sequence view of a three-dimensional object, records it using a holographic method, and realizes a quasi-three-dimensional display of the original object when it is reproduced. Synthetic holography can be divided into two categories: optical synthetic holography and computational synthetic holography. In 1970, M.C.King et al. made a synthetic hologram by optical interference method. Computational synthetic holography was proposed by Japanese scholar Yatagai in 1976. The Fourier transform hologram of each view is generated by computer, and the elementary holograms are arranged according to the order of observation, and finally a synthetic hologram is obtained. The reproduction of the hologram requires a single Color laser illumination is transformed by a Fourier transform lens an...
