Rephaser or Repather is a reaction found by Peter Raynham in 1973 that shifts the phase and path of a pair of gliders.[1] The reaction involves a block catalyzing the evolution of an interchange predecessor, reflecting both gliders by 90 degrees.

There is another form of this reaction, glider-block cycle, that reflects the gliders 180 degrees.
More generally, any mechanism that changes the phase and path of a glider or spaceship may be referred to as a rephaser, especially any reflector (A) that makes a glider arrive on a different time compared with reflecting with reflector B. For example, in the process of constructing and reducing the original period-52 glider gun, two bumpers in a 180-degree turn can be used as a rephaser to get a glider stream of repeat time 52 to the same place that two Snarks could, but arriving at a time impossible to do with the Snark.
