一、概述从十八世纪初开始研制感光片以来,至今已有二百年的历史。由于科学技术的不断发展,特别是近三、四十年来光化学技术的迅速进展,作为图象记录的最经济、方便的手段之一的感光片的生产和应用也获得了迅速发展。不但产量增加,品种增多,质量提高。而且应用领域也日趋广泛。目前不仅应用在常规的照相电影行业中,而且在教育、医疗、物质分析、天文、航测遥感以及军事上都已离不开感光片。所以感光片已日益显示出它的普遍性和重要性来,成了一门独立的学科和工业分支。
I. Overview From the beginning of the eighteenth century development photosensitive film, so far, two hundred years of history. Due to the continuous development of science and technology, especially the rapid progress of photochemical technology in the last three or four decades, the production and application of photosensitive films, one of the most economical and convenient methods for image recording, have also been rapidly developed. Not only increased production, increased variety, quality improvement. And applications are also increasingly widespread. Currently not only used in the conventional photographic industry, but also in the education, medical, material analysis, astronomy, aerial survey and remote sensing and military are inseparable from photosensitive film. So sensitive film has increasingly shown its universality and importance to become an independent branch of the discipline and industry.
