Abstract: In multi-heterodyne interferometry, the non-ambiguous range (NAR) and measurement accuracy are limited by the generation of synthetic wavelengths. In this paper, we propose a multi-heterodyne interferometric absolute distance measurement based on dual dynamic electro-optic frequency… read more here.

DOI: 10.3788/col202523.073901
Abstract: The acousto-optic modulator (AOM) plays an important role in heterodyne interferometric sensing, and it is always regarded as an ideal optical frequency shifter. In this paper, we compare the effects of its residual zero-order diffraction… read more here.
