Abstract

A temporary or permanent safe line projection system comprises a stationary or movable structure that is dimensioned and arranged to be supported by and project upwardly from an athletic field surface (or other surfaces needing delineation). A laser source is supported by the movable or stationary structure and is maintained by the movable or stationary structure at an elevated location relative to the athletic field surface (or other surface needing delineation). This allows the laser source to direct safe optical energy downward upon the field while the movable or stationary structure is maintained substantially in a first orientation relative to the athletic field surface (or other surfaces desiring delineation). A sensing arrangement is operative to to disable the laser source or modulate its output depending upon proximity of users to the system or its output and upon ambient lighting conditions, as the case may be.
