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…
An original classification of obscuration-free telescopes designs unfolded in two dimensions
Benjamin Aymard, Andrea Delahaye, Audric Drogoul
In this article we propose an original classification method for unobscured imaging systems unfolded in two dimensions. This classification is based on a study of off-axis properti…
Oscillating Turing patterns, chaos and strange attractors in a reaction-diffusion system augmented with self- and cross-diffusion terms
Benjamin Aymard
In this article we introduce an original model in order to study the emergence of chaos in a reaction diffusion system in the presence of self- and cross-diffusion terms. A Fourier…
Bifurcation analysis and steady state patterns in reaction-diffusion systems augmented with self- and cross-diffusion
Benjamin Aymard
In this article, we carry out a study of long-term behavior of reaction-diffusion systems augmented with self- and cross-diffusion, using an augmented Gray-Scott system as a genera…
On pattern formation in reaction-diffusion systems containing self- and cross-diffusion
Benjamin Aymard
In this article we propose a unified framework in order to study reaction-diffusion systems containing self- and cross-diffusion using a free energy approach. This framework natura…
