conference on current developments in Lens design and optical engineering XI - and Advances in Thin Film Coatings VI
作者: Brueckner, Andreas Duparre, Jacques Wippermann, Frank Leitel, Robert Dannberg, Peter Braeuer, Andreas Fraunhofer Inst Appl Opt & Precis Engn D-07745 Jena Germany
Although several applications of machine vision and biomedical imaging ask for the close-up imaging of extended object fields, only few, mostly bulky solutions exist. We demonstrate the optical design and realization ... 详细信息

8th conference on current developments in optical design and optical engineering
作者: Ferreira, MFS Univ Aveiro Dept Phys P-3800 Aveiro Portugal
We have examined the main constraints on the design of single-channel, high-capacity soliton communication systems. Ln the average soliton regime, the Gordon-Haus timing jitter limits the bit rate to less than 7 Gb/s ... 详细信息

作者: Suarez-Romero, Jose G. Salas-Zuniga, Roberto Inst Tecnol Queretaro Av Tecnol SN Esc Escobedo Queretaro 76000 Qro Mexico Ctr Ingn & Tecnol SC Queretaro 76090 Qro Mexico
This work considers typical radiometers that measure the radiance of sources or of some surface (due to reflection). The most important thing in a radiometer is its optical cavity, which defines the solid angle of mea... 详细信息

作者: Sure, T Wesner, J Heil, J Leica Microsyst GmbH D-35578 Wetzlar Germany
We discuss the requirements on design and production regarding geometric and chromatic aberrations for objectives used in 4Pi confocal microscopy. We show that even the selection of a category 1/1 glass will not autom... 详细信息

作者: Bociort, Florian van Turnhout, Maarten Marinescu, Oana Delft Univ Technol Opt Res Grp Lorentzweg 1 NL-2628 CJ Delft Netherlands
Saddle-point construction (SPC) is a new method to insert lenses into an existing design. With SPC, by inserting and extracting, lenses new system shapes can be obtained very rapidly, and we believe that, if added to ... 详细信息
