| Abstract: | A method of measuring the velocity of fast moving object by charge coupled device (CCD) shadow photograph system is developed. This system consists of high resolution orthogonal CCD cameras, time detecting device and the pulsed laser which can generate two short laser pulses with adjustable interval more than 100 μs. Experiments are conducted to measure the velocity of the flying steel ball. The results show that the proposed velocity measurement is effective in modern ballistic measurement. |
