| Abstract: | Measurement of relative velocity of moving objects is needed in various applications.A novel device for direct measurement of relative velocity of vehicle is described. The device senses the light reflected from road surface by two optoelectronic detectors. The velocity is determined by the correlation of two signals from two (optoelectronic) detectors. |

| Keywords: | velocity measurement optoelectronic detector noise-like signal |
