Abstract
A laser-based line projection system that is suitable for selectively placing lines on a floor surface, such as a factory floor. Several projectors are used in a typical installation. Each projector includes a laser directed through a diverging lens to create a planar projection of laser light. The planar projection creates a bright line when it falls on a surface. Each projector is optionally equipped with a movable mask that alters the angle of divergence for the laser light after it passes through the cylindrical lens. This component allows the projector to vary the length of the line projected.
