Laser Scanner Reverse-Engineers Automotive Panels

Aftermarket automotive manufacturers usually must visit automaker facilities to preview new automobile models. They often are given just a couple of hours to take enough measurements to ensure that they can build products that mesh with vehicle dimensions. When engineers at Infinity Products in Minneapolis -- which makes consoles that mount DVD and VCR screens to vehicle ceilings, as well as decorative instrument panel overlays -- used a portable coordinate measuring machine to reverse-engineer parts, the limited number of data points measured meant that it often took weeks to build a...Read full article

    laser triangulation
    A technique that uses a solid-state laser and a detector to determine an object's relative distance to the system. The laser beam is projected onto the target and then reflected onto a detector through the means of focusing optics. When the laser beam moves on the detector, information is stored into binary code to later be processed and used for calculating the relative distance.

    1. A device used to trace out an object and build up an image. One of the most common of these types is video scanning. The scanning takes place inside the television tube as electrons, guided by electron optics, sweep linearly across a tube face coated on the inside with a phosphorescent material. A scanner can convert a paper drawing or photograph into pixels on a display screen. Scanners are also used to relay information in optical data processing. 2. A device that automatically measures or...
