专利汇可以提供Computer-aided laser-based measurement system专利检索，专利查询，专利分析的服务。并且A system having laser source and radiation sensor assemblies electrically communicating with a computer is provided for rapid, remote sensing of the static, geometric and dynamic motion properties of a selected specimen. A laser beam incrementally scans the surface of a specimen to be evaluated in response to computer generated programmed signals and the radiation sensor follows the laser beam illumination as at the specimen surface. Both the source and sensor provide output signals representing the angular position of pointing of the source and sensor assemblies. The source and sensor angle signals are triangulated in the computer for calculation of desired geometric and dynamic specimen properties. The computer can be programmed to generate a display for presentation of the specimen properties or for governing industrial control, inspection or processing systems, that are related to the specimen properties measured.，下面是Computer-aided laser-based measurement system专利的具体信息内容。
