The Lorentz length contraction for a rod in uniform motion is derived
performing two measurements at arbitrary times. Provided that the
velocity of the rod is known, this derivation does not require the
simultaneous measurement of two events. It thus avoids uncomfortable
superluminal relationships. Furthermore, since the observer's simultaneous
measurement is not needed in order to observe spatial contraction,
this procedure is more akin to the Lorentzian relativity approach
and is better suited for more general schemes such as deformed spacetime
versions of special relativity. An example of a space contraction
measurement from the same rest position in the observer's frame illustrates
the procedure.
