The Stabilization Analysis of Automatically Adjustable Optical intensity System Using Iris Diaphragm;
采用可变光阑的自动调光系统的稳定性分析
In this method,light was adjusted by combining external trigger electronic shutter mainly and iris diaphragm assistantly.
该方法采用外触发电子快门和可变光阑相组合的方式进行调光,外触发电子快门调光为主,可变光阑调光为辅。
Because of the illuminance of external world change with train working, we can change the iris diaphragm size and adjust shutter exposure time access to the best of the CCD exposure, So as to achieve good results observed.
最后对可变光阑进行设计,完全满足实际使用要求。
With the combination of an electronic shutter and a variable diaphragm in a CCD video camera system, light is adjusted automatically under the control of a single chip microcomputer.
在CCD摄像系统中,利用电子快门和可变光阑有机结合,在单片机控制下实现全自动调光,不仅扩大了调光的动态范围,而且可有效地控制对运动目标摄像时产生的像移,其最大像移控制在0 0024mm。
