But recording these images requires a high emission energy exposure 15-60 times longer than that demanded by ordinary photography. The use of high emission energy, especially in the case of UV, might be destructive to surface-forming materials. This is one of the greatest disadvantages of these methods. Introduction of the Vidicon camera, utilizing a television system, makes it possible to produce in a few seconds images using very weak lighting or low radiation emissions and thus permitting the experimental combination of the above two methods, termed here the "Raking Ultra-Violet Method". It is possible, using this new technique, to distinguish minute differences of thickness such as are found in printing ink, oil stamp, or color layers, for example. It is known that UV radiation may cause particular fluorescences from some materials. Incorporating this effect with the raking UV technique should increase its potential usefulness in research on museum collections.}, pages = {815--823}, title = {文化遺物における製作技術調査法としての紫外線側光の利用について}, volume = {6}, year = {1982}, yomi = {モリタ, ツネユキ} }
