A facsimile scanner in which each successive line of an original is scanned by firing a light-reflective or light-refractive spherical projectile along a path over which an optical image of that line is formed to produce a time-varying pattern of reflected or refracted light from the projectile as it traverses the path. A photodetector responsive to light diverted from the projectile provides the facsimile signal. In the recording mode, each successive line of a facsimile signal is recorded by illuminating the same projectile with light modulated by the facsimile signal as the projectile traverses its path to produce a spatially varying pattern of reflected or refracted light, an optical image of which is formed on a recording medium such as the photoconductor of an electrophotographic copier. The rate at which the photodetector output is sampled in the scanning mode and at which the facsimile signal is fed to the modulator in the recording mode is adjusted for the actual measured velocity of each successively fired projectile.
