在加色法印片过程中,需要有一种机构,它能对从白光中分出的红、绿、兰三原色光强,按照予先确定的程序,进行自动地、准确地调制,这种机构就是光阀。光阀在加色法程控调光印片机中占有很重要的地位。所谓程控印片机,指的是用数字程序控制手段来控制光阀进行自动地、准确地调光,而不是控制别的部分。光阀的跳光时间,光阀叶片开启或关闭相应光号的不重复误差,以及光阀的光号性能(即印片机的光号效率)等技术指标,直接影响着影片的质量和生产率。所以设计出满足印片机技术要求的光阀机
In the process of additive color printing, there is a need for a mechanism that automatically and accurately modulates the light intensities of the three primary colors red, green and blue separated from the white light in accordance with a predetermined procedure Light valve. Light valve in the additive process control dimmer printer occupies a very important position. The so-called program-controlled printer, refers to the digital program control means to control the light valve automatically and accurately dimming, rather than control other parts. The time when the light valve is jumping off, the non-repetition error of the corresponding light number when the light valve leaves on or off, and the light signal performance of the light valve (ie, the light number efficiency of the printer) directly affect the quality and productivity of the film . So designed to meet the technical requirements of the printer light valve
