Even though photographic emulsions exist that are capable of attaining the theoretical resolution for a given wavelength of light, the lack of reliability in recording conventional images at very high reduction ratios has tended to limit greatly the useful storage density of photographic film. Holographic recording techniques offer a means for attaining the necessary reliability, thereby making the recording of many pages at high reduction ratios feasible. Some tasks that are difficult in conventional recording are in fact quite easy in holographic recording. Generally, the characteristics of holographic recording are very different from recording conventional microimages. We discuss the techniques and problems of holographic ultrafiche recording and indicate our progress in this area.
尽管存在能够达到给定波长光的理论分辨率的照相乳剂，但在以非常高的缩小比例记录传统图像时缺乏可靠性，这在很大程度上限制了照相胶片的有用存储密度。全息记录技术提供了一种获得必要可靠性的方法，从而使以高缩小比例记录多页内容成为可行。一些在传统记录中困难的任务在全息记录中实际上相当容易。一般来说，全息记录的特性与记录传统微图像有很大不同。我们讨论全息缩微胶片记录的技术和问题，并指出我们在这一领域的进展。
