An integrated system generates a model of a three-dimensional object. A scanning laser device scans the three-dimensional object and generates a point cloud. The points of the point cloud each indicate a location of a corresponding point on a surface of the object. A first model is generated, responsive to the point cloud, that generates a first model representing constituent geometric shapes of the object. A data file is generated, responsive to the first model, that can be inputted to a computer-aided design system.

[ What is claimed is:] [1.]1. A system for calibrating the timing electronics in a device which requires monitoring the time of flight of the output pulses transmitted from a laser to a remote target and back to a detector, the output of which is supplied to the timing electronics comprising:a single mode optical fiber with one end of the fiber positioned to periodically receive the output pulses of the laser, said single mode optical fiber having a known length and wherein partial reflectors are located at each end of the optical fiber such that for each laser pulse entering the fiber a train of pulses will exit the fiber, said pulses being directed to the detector, said detector generating output signals in response thereto, said signals being passed through the timing electronics; anda processor for calculating a theoretical length of the fiber based on the detection of the train of pulses exiting the fiber and comparing that calculated length with the known length of the fiber to calibrate the timing electronics to improve the accuracy of the time of flight measurements of the laser pulses sent to and returning from the remote target.
