Joint digital optical Design of complex lenses using a surrogate image quality criterion adapted to commercial optical Design software
Applied Optics, 2018Co-Authors: Marieanne Burcklen, Herve Sauer, Frederic Diaz, Francois GoudailAbstract:Like classical optical Design, Joint digital-optical Design of complex lenses requires a skilled optical Designer helped by powerful optical Design software. Consequently, if optimization criteria have to be modified to take into account digital post-processing, the convenient optimization environment provided by commercial optical Design software needs to be preserved. For that purpose, we define a Joint-Design criterion based on a merit function that contains terms classically implemented in optical Design software but used in a non-standard way. After validation on a simple Design problem, the proposed method is applied to the Design of a very fast (f/0.75) complex lens. The obtained Joint-Designed lens is shown to be superior to a classically Designed one in terms of weight and image quality in the field.

On Energy Efficient Hierarchical Cross-Layer Design: Joint Power Control and Routing for Ad Hoc Networks
arXiv: Information Theory, 2007Co-Authors: Cristina Comaniciu, H. Vincent PoorAbstract:In this paper, a hierarchical cross-layer Design approach is proposed to increase energy efficiency in ad hoc networks through Joint adaptation of nodes' transmitting powers and route selection. The Design maintains the advantages of the classic OSI model, while accounting for the cross-coupling between layers, through information sharing. The proposed Joint power control and routing algorithm is shown to increase significantly the overall energy efficiency of the network, at the expense of a moderate increase in complexity. Performance enhancement of the Joint Design using multiuser detection is also investigated, and it is shown that the use of multiuser detection can increase the capacity of the ad hoc network significantly for a given level of energy consumption.
