A laser spot is projected perpendicular or in an angle onto a target surface. The detector (receiver) is located at an angle relative to the laser spot on the surface (Emitter). A change in height on the surface in z causes a change in x on the detector. The internal controller automatically adjusts the exposure time based on the surface reflectivity.
