A one-time reflector is a constellation or other pattern that can be hit by a glider to produce another glider travelling in a different direction. This contrasts with permanent reflectors, which will survive and can be reused to reflect further gliders; and with one-time converter, which produces an output different from the input.
One-time reflectors are an important component for slow salvo synthesis, where they are frequently used to change the direction from which a target glider will hit the reaction site.
If a constellation upon being hit by a glider instead produces a glider travelling in the same direction, it is known as a (one-time) rephaser.
The simplest one-time reflectors are boat, eater 1, and toad, any one of which of which can turn a glider 90°, long ship, which can reflect a glider 180°, and long boat, which can reflect a glider either 90° or 180°. There are also two small one-time turner constellations, each made up of two blocks; one of these turns a glider 90° and the other produces a 180° turn.
