Subdivision of Nonlinearity in Heterodyne Interferometers
A significant finding was that, like the subdivision of wavelength, the nonlinearity of the heterodyne interferometers, in term of length, is also subdivided by the multiple of the optical path. This gives us ...

Investigation and Compensation of the Non-linearity of Heterodyne Interferometers
The non-linearity of heterodyne interferometers is mainly influenced by the non-orthogonality and ellipticity of the linearly polarized partial beams of the laser and by the limited extinction capability of th...
