摘要：

As part of the intelligent processing efforts of the Spray Forming Technology Group at the David Taylor Research Center, a laser stripe sensor has been implemented to monitor preform characteristics. The preform surface roughness is measured in real time and the correlation to preform quality in terms of porosity levels is assessed. The laser stripe method is not a direct indicator of quality, but it can be used with other sensors and advanced control techniques for control of the spray-forming process.
