Measurement of high speed event using pulsed speckle interferometry
This paper presents a new method, i. e., pulsed speckle interferometry, in the measurement of high speed event. To measure the velocity of objects moving at a speed as high as 100 m/s, the single pulse ruby laser beam is divided into double pulses beam by a splitter and by an optical delay line.
