ABSTRACT:
An apparatus for verification of corrected surfaces or surfaces being corrected includes a carriage displaceable on an horizontal alignment and displacement guide supported on two vertical supports, a proximity gage mounted on an extendable arm of the carriage, and a collimated laser-transmitter mounted on one of the two supports and cooperating with a multiple sensor screen mounted on the carriage. The proximity gage measures the distance between the proximity forming part thereof and a correct surface, and the laser-transmitter measures the distance from the one support to the carriage. A control system processes the measuring data and generates a graphic representation of the processed data.
