Study on Aberration Correction of Adaptive Optics Based on Convolutional Neural Network
Photonics, 2021 The existence of aberrations has always been an important limiting factor in the imaging field. Especially in optical microscopy imaging, the accumulated aberration of the optical system and the biological samples distorts the wavefront on the focal ...

Holographic aberration correction: optimising the stiffness of an optical trap deep in the sample [PDF]
, 2011 We investigate the effects of 1st order spherical aberration and defocus upon the stiffness of an optical trap tens of μm into the sample. We control both these aberrations with a spatial light modulator. The key to maintain optimum trap stiffness over a

Effect of Outer Polepiece Shroud Geometry on Bipolar Lens and Studying its Properties
Tikrit Journal of Pure Science, 2022 In this paper, several innovative designs of axially symmetrical magnetic dipole lenses, which are bipolar lenses with different geometries, were designed, where the outer pole arm indicated by the symbol was changed (hp) with current density (σ = 6 A ...
