1. A system for sensing relative motion of a target, comprising:

  • one or more transmitters that transmit one or more light patterns;

    one or more receivers that detect the one or more light patterns;

    one or more memory devices for storing instructions; and

    one or more processor devices that execute the instructions that enable actions, including;

    employing the one or more transmitters to transmit the one or more light patterns to the target, wherein the one or more transmitters scan the one or more light patterns across the target in one or more directions;

    employing the one or more light patterns to generate a pattern on the target, wherein a rotation of the pattern is controlled by modulating the one or more light patterns;

    employing the one or more receivers to detect one or more reflected light patterns from the target and generate one or more signals that correspond to the one or more reflected light patterns;

    employing the one or more signals to determine at least one of a spatial elongation or contraction of the one or more reflected light patterns in the one or more directions;

    providing one or more characteristics of a relative velocity between the target and the one or more receivers based on at least one of the determined spatial elongation or the determined contraction of the one or more reflected light patterns; and

    providing a magnitude of the relative velocity based on one or more portions of the rotation of the pattern that are associated with one or more maximums of the spatial elongation or contraction of the one or more reflected light patterns.
