感光材料的感光性能测试是一项比较繁琐的工作,特别是彩色感光材料的感光性能测试更是如此。一般同一条样品必须测三次,以便得出感红、感绿、感蓝三层的感光特性曲线,并由此求出相应的感光度,最佳偶合反差等参数。当测试样品量大的时候,人为误差的可能性也增大,而且,即使同一样片,不同的人测试,其结果也有差别。为了解决这一问题,我研究所购买了一套带微处理器的美国COSAR密度计(能自动转换滤色片)及IBM计算机(带打印机和绘图仪),本人研制了连 Photosensitive material sensitivity test is a more cumbersome work, especially the sensitivity of color light-sensitive materials testing even more so. In general, the same sample must be measured three times in order to get the sensitometric curve of red, green and blue, and the corresponding sensitivities and the optimal coupling contrast are obtained. When the test sample size is large, the possibility of human error is also increased, and even the same sample, different people test, the results are also different. To solve this problem, I Institute purchased a set of US COSAR densitometer with microprocessor (automatic color filter conversion) and IBM computer (with printer and plotter), I developed even with
