Journal ArticleDOI
Design, fabrication and testing of microlens arrays for sensors and microsystems
TL;DR: In this article, the authors report on their activities in design, fabrication, characterization and system integration of refractive microlens arrays for sensors and microsystems, including neural networks and multiple pupil imaging systems for photolithography.
Journal ArticleDOI
Microoptical telescope compound eye
Jacques Duparré,Peter Schreiber,Andre Matthes,Ekaterina Pshenay-Severin,Andreas Bräuer,Andreas Tünnermann,Reinhard Völkel,Martin Eisner,Toralf Scharf +8 more
TL;DR: A new optical concept for compact digital image acquisition devices with large field of view is developed and proofed experimentally and anamorphic lenses, where the parameters are a function of the considered optical channel, are used to achieve a homogeneous optical performance over the whole field of sight.
Journal ArticleDOI
Comparing glass and plastic refractive microlenses fabricated with different technologies
Heidi Ottevaere,R. Cox,Hans Peter Herzig,Takaaki Miyashita,Kris Naessens,Mohammad R. Taghizadeh,Reinhard Völkel,H.j. Woo,Hugo Thienpont +8 more
TL;DR: In this article, the most important fabrication techniques for glass and plastic refractive microlenses and corresponding state-of-the-art micro-lenses, which were obtained from selected research groups, were reviewed and discussed.
Journal ArticleDOI
Miniaturized imaging systems
TL;DR: In this paper, the authors look how nature has successfully solved similar problems in the case of very small creatures and show how some of nature's ideas might help further miniaturize micro-cameras.
Proceedings ArticleDOI
Theoretical analysis of an artificial superposition compound eye for application in ultra flat digital image acquisition devices
TL;DR: In this paper, a paraxial 3x3 matrix formalism is used to describe the arrangement of three microlens arrays (MLA) with different pitches to find the first order parameters of the system.
