Exoplanet detection with simultaneous spectral differential imaging: effects of out-of-pupil-plane optical aberrations [PDF]
, 2006 Imaging faint companions (exoplanets and brown dwarfs) around nearby stars is currently limited by speckle noise. To efficiently attenuate this noise, a technique called simultaneous spectral differential imaging (SSDI) can be used.

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 ...
