X Resolution

X resolution is the horizontal distance between each measurement point along the laser line. This specification is based on the number of camera columns used to cover the field of view (FOV) at a particular measurement range.

Because the FOV is trapezoidal (shown in red, below), the distance between points is closer at the near range than at the far range. This is reflected in the Gocator data sheet as the two numbers quoted for X resolution.

X Resolution is important for understanding how accurately width on a target can be measured.

When the sensor runs in Profile mode and Uniform Spacing is enabled, the 3D data is resampled to an X interval that is different from the raw camera resolution. For more information, see Uniform Data and Point Cloud Data.
