| Abstract: | Method and principle of on-line velocity measurement of mobile objects by using correlation technique is introduced.By means of ingenious measurement of correlative signals upstream and downstream,passing time of corresponding peaks of correlative signals is computed and the motion velocity of rolled objects is indirectly meansured.A practicable non-contact on-time correlation velocimeter is developed.This velocimeter has already used for measurement of motion velocity of hot-rolled steel in Ma'anshan Steel Works. |
