彩虹全息的三缝效应方法可以保存彩色胶片。虽然全息图是黑白底片,但通过白光观察却可以复原所保存的彩色像。显然这种黑白底片不存在彩色胶片保存时间长不了的问题。我们提出一种新方法,仅利用一种波长的激光(λ=6328A)代替通常要用红、绿、兰三种不同波长的激光,成功地进行了彩色图象记录。实验方法是首先用红绿兰三个滤色片获得同一物体的三张不同灰度分布的黑白底片(分色底片)。然后用一步虹全息的方法记录。
Rainbow holographic three-stitch effect method can save color film. Although the hologram is a black and white film, but through the white light observation can restore the saved color image. Obviously there is no black-and-white film color film storage time can not long the problem. We propose a new method of successful color image recording using only one wavelength laser (λ = 6328A) instead of the laser usually used in three different wavelengths, red, green and blue. The experimental method is to obtain three black and white films (color separation films) of the same object with three color filters of red, green and blue first. Then use one-step holographic method of recording.
