Abstract
A new transient spectrum detection method with high time resolution based on area CCD is proposed. By reforming and mending working sequence of CCD, utilizing principle of frame restore, linear spectrum detection with high time resolution was achieved. This method improves frame rate and time resolution of CCD greatly. LED impulse light experiment is performed to demonstrate feasibility of the method. Experiment results show that this transient spectrum acquisition method based on area CCD is efficacious, detection frame rate can be as high as 10Mfps. Time resolution is less than 100ns, and can be able to image 2048 times continuously. The experiment is of importance to expand application of CCD in the transient spectrum detection area.
