制作彩色全息图存在一系列困难。困难系由采用不同谱带的相干辐射源使全息图的记录复杂化、记录必须使用多张照相底片以及对感光材料的处理过程需要多道工序等原因所致。目前获得彩色全息图最常用的方法有两种:a)在被分成若干独立区域的感光材料表面上制作全息图;以一种波长在每个区域内
There are a number of difficulties with making color holograms. Difficulties are caused by the complexity of recording holograms with coherent radiation sources using different spectral bands, the need to record multiple photographic films and the multiple processing steps required to process the photosensitive material. There are currently two most commonly used methods for obtaining color holograms: a) making a hologram on the surface of a light-sensitive material that is divided into a number of individual areas; using a wavelength in each area
