(4) Once we have the normal curvature kn, we then calculate the partial derivative of kn w.r.t. λ to obtain the principal curvatures k1, k2. The details are presented in the supple- mentary. While this approach works accurately and effi- ciently in practice, we observed that...
The primary question in this research is whether Curvature Weighted Decimation introduces less elevation error than Random Decimation for the same decimation percentage and how to characterize that improvement. In addition, a derivative question is whether and how much the selected method split influences...
Photothermal interferometry (PTI) is a derivative of LAS and is a highly sensitive spectroscopic technique for trace gas detection [8]. The photothermal (PT) process involves localized heating generated from the relaxation of the ro-vibrational state of gas molecules via molecular collisions [9]. ...
