DOI: 10.1016/j.optlaseng.2018.12.001
Abstract: Abstract We propose a purely automatic and accurate phase aberration compensation method in digital holographic microscopy for phase-contrast imaging of living cells. At first, a least-squares fitting procedure is implemented to correct a large proportion… read more here.

DOI: 10.1016/j.optmat.2020.110284
Abstract: Abstract Metasurfaces for chromatic aberration compensation have attracted a lot of research attentions since almost all imaging systems suffer from the intrinsic dispersion of composite materials and the chromatic aberration. However, most of them rely… read more here.

DOI: 10.1364/ol.43.005993
Abstract: We present fiber Bragg gratings (FBGs) fabricated using adaptive optics aberration compensation for the first time to the best of our knowledge. The FBGs are fabricated with a femtosecond laser by the point-by-point method using… read more here.
