That is hilarious outlook2020. There are a few seriously deep flaws in your take on the difference between melt-pool and global-part optical imaging vs thermal. The NIST paper is proposing using all the tools available (both optical and thermal) to perform both a real-time evaluation of the part build, and a near-real-time software based platform to perform nearly live build simulation based on the real-time data being gathered. They in no way are even close to proposing optical only real-time data gathering...not even close.

All the best,
