By comparison, the noncontact and automated Laser Radar system can satisfy all of the following metrology
aspects: t Quality assurance applications, including part-to-CAD comparison, feature and gap & flush inspection
t Routine and event-driven inspection such as first-article inspections, incoming and outgoing inspection, and troubleshooting failure investigations
t In-process applications, such as component alignment and robotic positioning
t Tool building and alignment, including locating and adjusting tool features in real time
t Tool digitalization and documentation of as-built tools and die surfaces
t Model digitalization, including scanning artistic models and performing design layups for in-process and outgoing quality assurance
t Routine maintenance, including static and dynamic inspections of tooling assemblies

t Portability. Do parts need to be measured on the factory floor, in-process, or delivered to a controlled-environment metrology department. Do you require a separate metrology lab and/or a production inspection solution as parts are being made? Will a portable solution bridge the gap, if needed?
t Automation. The ability to automate and run untended can result in lower manpower costs and is ideal for repetitive tasks.
t Data-acquisition speed and software compatibility. The nonstop growth in computing power has made many advances in inspection possible. Is report data available in easily understood forms? Can reporting be completed offline, leaving articulated arms or CMMs dedicated to inspection tasks?
t Cost.
Utility-scale alternative energy projects are appearing all over the world. Earlier this year, First Solar Inc. (Tempe, AZ) and Southern California Edison (SCE; Rosemead, CA) an- nounced purchase agreements for the off-take of electricity generated by four solar projects totaling 500 MW. The deals establish Southern California Edison as the largest single off-taker of energy from First Solar projects in the world. The agreements are for power generated by projects in Califor- nia, Nevada and Arizona, all currently in development by First Solar, with anticipates the projects to be commissioned by the end of 2019.
The utility also has a long-term agreement for 250 MW of capacity of the 550-MW Desert Sunlight Solar Project in Desert Center, CA, which was commissioned in 2014. SCE has additional contracts in place for other projects currently under construction, including the Desert State- line project in California and the Silver State South project in Nevada.
As photovoltaics, wind, and other energy projects grow
more competitive with conventional generation, inspection technologies need to contribute to production efficiencies while assuring critical quality targets. Laser Radar is a unique response to this growing segment.
