摘要

Device for reproduction of rapid movement by observation of the pattern circular, and a process for the implementation of the device. / p & & p & this device comprises at least one pattern 14, a video camera 20 and a flash lamp 22 which is synchronized to the images of the camera 20 by a triggering circuit 24. An electronic box 26 for processing the video signal provides an analog / digital conversion, a compression and a coding of the video signal. The encoded video signal is transmitted by transmission means 28 to the means for analyzing and processing and display 30 the transmitted coded signal. The compression of the signal consists in extracting the contours of the images recorded by the camera 20. / p & & p & application to the restoration of the movement of a body 10 to be released from a launcher 12.
