Mobile pico projectors need to project on surfaces at a variety of distances, for which different throw angles produce optimal image size and brightness. By electronically adjusting the peak drive voltage to our 1‐mm x 9‐mm scanning fiber engine, we demonstrate rapid (resolution‐maintaining) rescaling of throw angles up to 100°.
