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.
