ANTARIS sensors measure displacement. Depending on sensor combination and placement you may measure thickness, width, height, length, straightness, flatness, profile or diameter. Based on a Digital Signal Processor (DSP) the intelligent sensor controls the exposure of the CCD and the output power of the laser source. Due to this, LAP laser sensors measure extremely quickly and precisely, even if surface characteristics like colour or reflectivity are changing.
Virtually all materials can be measured, even hot and glowing surfaces. Parameter like measurement speed or filters are handled directly in the sensor”s DSP.

PROFILE and GAP MEASUREMENT for all industries

OPTARIS M is a family of laser light section sensors. They measure the height profile of an object by projecting a laser line on its surface which is captured by a camera element from a specific angle. All geometrical changes of the surface, like edges, angles, gaps, grooves or curvatures generate deformations of the straight line from the cameras angle of view. The real coordinates can be calculated by the size of the deviation. For objects moving through the measuring field this process produces a complete 3D height profile.
