recommendations! Published in 2017 at "Science China Earth Sciences"

DOI: 10.1007/s11430-016-5127-8

Abstract: Based on the theory of information entropy concerning nonlinear errors, the growth rules for the nonlinear errors of the Lorenz system and its predictable components are studied. The results show that the impact of the… read more here.

DOI: 10.1016/j.optcom.2018.12.030

Abstract: Abstract After a long-term research, the birefringence-Zeeman dual-frequency (BZDF) laser has entered the practical stage, and the BZDF laser interferometer has more powerful displacement and size measurement functions, especially the near-zero nonlinearity. This paper theoretically… read more here.

DOI: 10.1364/oe.25.004470

Abstract: In order to compensate the nonlinear error of a heterodyne interferometer caused by both frequency mixing and phase demodulating electronics in real time, a novel iterative algorithm with a digital lock-in phase demodulator is proposed… read more here.

DOI: 10.1364/oe.527440

Abstract: This paper discusses the generation of a novel periodic nonlinear error in homodyne interferometers due to geometric misalignments. These misalignments arise from cumulative assembly errors among the sensor head interior, target mirror, test platform, and… read more here.
