Wavefront sensing for aberration modeling in fluorescence macroscopy [PDF]
2011 IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2011 In this paper, we present an approach to calculate the wavefront in the back pupil plane of an objective in a fluorescent MACROscope. We use the three-dimensional image of a fluorescent bead because it contains potential pupil information in the ‘far' out-of-focus planes for sensing the wavefront at the back focal plane of the objective.

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 ...
