Due to the increasing dimension, complexity and cost of the future astronomical surveys, new technologies enabling more compact and simpler systems are required. The development of curved detectors allows to enhance the performances of the optical sy

La courbure de capteurs d’image : une amélioration astronomique ?

Autor: Emmanuel Hugot

Publikováno v: Photoniques. :36-39

Étudiée pour la première fois par la NASA au début des années 2000, l’idée de pouvoir modifier la forme des composants semi-conducteurs afin qu’ils épousent la surface focale d’un système optique a intéressé nombre d’acteurs mondiau

Publikováno v: Applied Sciences, Vol 10, Iss 2, p 712 (2020)

In the present paper, we discuss the design of a projection system with curved display and its enhancement by variably adjusting the curvature. We demonstrate that the focal surface curvature varies significantly with a change of the object position

International audience; Additive manufacture (AM), also known as 3D printing, builds an object, layer-by-layer, from a digital design file. The primary advantage of the layer-by-layer approach is the increase in design-space, which enables engineers

International audience; The new degrees of freedom offered by the new family of freeform surfaces helps compensating for off axis aberrations in optical designs. We define a freeform surface as a non-rotationally symmetric surface which cannot be des
