Abstract
A structured light generator for illuminating a scene comprising a light source and a light guide comprising a tube having a longitudinal axis and having substantially reflective sides arranged to project an array of distinct images of the light source towards the scene in the manner of a kaleidoscope, wherein including a light deflection element to redirect light so that the projection axis and the light guide axis are angled with respect to one another. In this way the light guide, which is typically an elongate structure, can be ‘folded’ away from the direction of light projection, which offers advantages in terms of packaging of the light generator where thickness in the direction of projection is desirably minimised.
