低成本CMOS阵列式高速成像系统

高速摄像是研究瞬间发生的物理和化学现象的重要手段之一.针对碰撞过程,提出了应用低成本CMOS阵列式成像传感器构建高速摄像系统.成像阵列由16个可更换的CMOS单元组成,接在主板上.为了进行同步控制,实验研究了CMOS传感器的工作时序;通过延时器,使阵列式火花源分时闪光,并在CMOS快门打开的时间段内完成.实验表明,该系统可以实现对碰撞等瞬间发生过程的拍摄,为相关研究提供基础.

High-speed Imaging System with CMOS Array

High-speed imaging is on e of the important ways to study the physical and chemical phenomena occurred in stantaneously.A high-speed imaging system is constructed with a low-cost array of 16 CMOS imaging sensors that exist in a mainboard.Their control and processi ng circuits are independently in 16 sub-boards and are inserted in the mainboar d to form a uniform system.To make the array grasp a sequence of images correctl y,sync control is used to the working sequence of the CMOS array experimentally. Under the control of a delayer,the spark source array gives off time-sharing sp arks during the CMOS shutter opened.The experiments indicate that an instantaneo us process like collision can successfully be grasped by the system.
