Abstract
A process tracking laser camera with non-eye-safe and eye-safe operating modes is disclosed. The camera has an image sensor with a field of view covering a target area of a workpiece. The camera also has first and second laser units for projecting respectively non-eye-safe and eye-safe laser beams towards the target area. A control unit has laser drivers for driving the laser units, a cut-off circuit operatively connected to the laser driver of the first laser unit for disabling its operation depending on a control signal, and a control circuit for controlling the laser drivers depending on a cut-off condition of the cut-off circuit controlled by a switch device so that the first laser unit is enabled and the second laser unit is disabled in the non-eye-safe operating mode while the first laser unit is disabled and the second laser unit is enabled in the eye-safe operating mode.
