Robust optical design and closed-form tolerancing through autodiff-based Hessian spectral analysis
Bastien Laville, Benjamin Aymard
Robust optical design demands quantitative knowledge of how manufacturing and alignment tolerances degrade system performance. We show that analysing the perturbation eigenmodes of…
The -achromat and beyond: a unified variational framework for optimal chromatic aberration correction
Bastien Laville, Benjamin Aymard
In this article, we present novel and effective methods for reducing chromatic aberrations in cemented lens systems. We derive an analytical solution coined the pentachromat, which…
Dynamic off-the-grid untangling of curves by Riemannian metric
Bastien Laville, Théo Bertrand
We propose an improved strategy for point sources tracking in a temporal stack through an off-the-grid fashion, inspired by the Benamou-Brenier regularisation in the literature. We…
Off-the-grid covariance-based super-resolution fluctuation microscopy
Bastien Laville, Laure Blanc-Féraud, Gilles Aubert
Super-resolution fluorescence microscopy overcomes blurring arising from light diffraction, allowing the reconstruction of fine scale details in biological structures. Standard met…
