Abstract
A light bead generating apparatus has a point light source (11) and a variable optical system (12, 13) of variable focal length, by means of which the point light source (11) is imaged via a light deflecting apparatus (24) in an image plane (14). The variable optical system is formed by two circular cylindrical mirrors (12', 13') which are crossed relative to one another, which have variable focal lengths in the direction of their circular cylinder axes (17', 18') and which are adjustable. They are illuminated by the image forming light beam (19, 19') in the direction of the optical axes (15).
