摘　　要：为了提高CCD的扫描速率并将其应用于百纳秒级瞬态超快现象的探测,提出一种基于面阵CCD的高时间分辨的瞬态光谱测量方法,并对其进行了实验验证.该方法采用帧存储的工作思路,对面阵CCD的工作时序进行改进,以实现高时间分辨率的探测.LED脉冲光实验结果表明,探测帧频可达10Mfps,时间分辨率达到100ns,并且能够连续成像2 048次.该方法对扩展CCD在瞬态光谱检测领域的应用具有借鉴意义.To raise the scan rate of CCD and apply to the hundred nanosecond scale transient phenomena detection, a transient spectrum detection method with high time resolution was proposed and demonstrated by experiment, based on area CCD. By reforming time sequence of CCD and utilizing principle of frame restore, detection with high time resolution was achieved. LED impulse light experiment was performed to demonstrate feasibility of the method. Experiment results show that this transient phenomena acquisition method based on area CCD is efficacious. Detection frame rate can be as high as 10 Mfps. Time resolution is less than 100 ns, and can be able to image 2 048 frames continuously. The experiment is of importance to expand application of CCD in the transient spectrum detection area.
