| 摘 要： | 针对基于硅基液晶(LCOS)的数码冲印系统,设计了一种LCOS的驱动电路。根据相纸感光乳剂的光密度特性和LCOS的电光特性,用误差最小迭代法算出电路所需的不同电压信号,实现红、绿、蓝三色电光响应曲线的平移、伸缩,使得三条曲线基本一致,从而达到数码冲印系统优化调整要求。

| Abstract: | Here is introduced a design of liquid crystal on silicon(LCOS) driver for the digital photofinishing system.According to the photo paper′ emulsion characteristic and the LCOS′s E-O characteristic,three set of circuit parameter was figured out by means of minimum mean squares algorithm.By applying these three set of parameter,the original LCOS′s E-O response curves for red,green blue light were trimmed to coincide with each other,which meets the requirement of digital minilab for optimal adjustment. |
