The diffractive achromat full spectrum computational imaging with diffractive optics
ACM Transactions on Graphics, 2016 Diffractive optical elements (DOEs) have recently drawn great attention in computational imaging because they can drastically reduce the size and weight of imaging devices compared to their refractive counterparts. However, the inherent strong dispersion

A comparative investigation on the use of compressive sensing methods in computational ghost imaging
, 2022 Paper 109900R, 10 S.Usually, a large number of patterns are needed in the computational ghost imaging (CGI). In this work, the possibilities to reduce the pattern number by integrating compressive sensing (CS) algorithms into the CGI process are ...

Deep learning in computational microscopy [PDF]
, 2019 We propose to use deep convolutional neural networks (DCNNs) to perform 2D and 3D computational imaging. Specifically, we investigate three different applications. We first try to solve the 3D inverse scattering problem based on learning a huge number of

Computational simulation of the intervertebral disc [PDF]
, 2013 The intervertebral disc is a complex structure unlike any other in the human body. The capability to withstand high loads and deformations in six degrees of freedom is facilitated by the unique soft tissue structures. However, the mechanical behaviour of
