Calligraphic projection is a system for displaying or projecting an image composed of a beam of light or electrons directly tracing the image, as opposed to sweeping in raster order over the entire display surface, as in a standard pixel-based display. Calligraphic projection is presently often used for laser lighting displays, whereby one or more laser beams draws an image on a screen by reflecting the laser beam from one or more mirrors attached to a deflecting mechanism.

Calligraphic projection is sometimes called Lissajous projection, after the mathematical figure (and mathematician).
