Research on the method of fast photoelectric diagnostics based on ordinary CCD

A novel method to realize fast photoelectric diagnostics using ordinary CCD is presented. By changing the mode of charge transfer of CCD, fast photoelectric diagnostics of single point with linear CCD and high-speed line scanning with array CCD can be achieved respectively. A fast photoelectric diagnostics system of single point based on linear CCD has been designed and fabricated to investigate the feasibility of this method. A pulsed blue light emitting diode (LED) has been used to measure the system. As a proof of concept, the rate of photoelectric diagnostics of single point reachs up to 20 MHz. The results demonstrated that the method of fast photoelectric diagnostics based on ordinary CCD is feasible.
