Methods for Performance Evaluation of Single Axis Positioning Systems: A New Standard

October 25, 2013
Author(s)
Ronnie R. Fesperman Jr., Nathan Brown, Kevin Elliott, Jonathan D. Ellis, Axel Grabowski, Steve Ludwick, Serge Maneuf, Brian O'Connor, Shane Woody
Many new high-precision linear and angular positioning systems are being used in emerging micro- and nanotechnology applications. Measuring and certifying the performance of these systems with off-the-shelf instrumentation and test methods suggested by

Morphing Metal-Polymer Janus Particles

October 25, 2013
Author(s)
Lewis M. Cox, Jason Killgore, Zhengwei Li, Zheng Zhang, Donna C. Hurley, Jianliang Xiao, Yifu Ding
Shape memory polymers have the unique ability to memorize and recover their permanent shapes after being programmed to hold high strain levels up to a few hundred percent. While studies have traditionally focused on utilizing shape memory effects for macro

Three-dimensional deep sub-wavelength defect detection using (lambda) = 193 nm optical microscopy

October 25, 2013
Author(s)
Bryan M. Barnes, Martin Y. Sohn, Francois R. Goasmat, Hui Zhou, Andras Vladar, Richard M. Silver, Abraham Arceo
Identifying defects in photolithographic patterning is a persistent challenge in semiconductor manufacturing. Well-established optical methods in current use are jeopardized by upcoming sub-20 nm device dimensions. Volumetric processing of focus-resolved

Towards Mobile Manipulator Safety Standards

October 24, 2013
Author(s)
Jeremy A. Marvel, Roger V. Bostelman
We present an overview of the current safety standards for industrial robots and automated guided vehicles (AGVs), and describe how they relate to the safety concerns of mobile manipulators (robot arms mounted on mobile bases) in modern manufacturing

A Literature Review of Sensor Ontologies for Manufacturing Applications

October 23, 2013
Author(s)
Craig I. Schlenoff, Tsai Hong Hong, Roger D. Eastman
The purpose of this paper is to review existing sensor and sensor network ontologies to understand whether they can be reused as a basis for a manufacturing perception sensor ontology, or if the existing ontologies hold lessons for the development of a new

A versatile bilayer resist for laser lithography at 405 nm on glass substrates

October 23, 2013
Author(s)
Quandou (. Wang, Ulf Griesmann
We describe a simple bilayer photoresist that is particularly well suited for laser lithography at an exposure wavelength of 405 nm on glass substrates, which is often used for the fabrication of binary diffractive optics and computer generated holograms

Exploiting dimensionality and defect mitigation to create tunable microwave dielectrics

October 23, 2013
Author(s)
Nathan D. Orloff, C H. Lee, T Birol, J A. Mundy, V. Goian, R. Haislmaier, E. Vlahos, Y. Kim, J. D. Brock, Y Zhu, R. Uecker, V. Gopalan, S. Kamba, X X. Xi, D A. Muller, I. Takeuchi, James C. Booth, C. J. Fennie
The miniaturization and integration of frequency-agile microwave circuits—tunable filters, resonators, phase shifters and more—with microelectronics offers tantalizing device possibilities, yet requires thin films whose dielectric constant at GHz

Laser and Photonic Systems Integration: Emerging Innovations and Framework for Research and Education

Bukkapatnam, Changquing Cheng, Soundar R. Kumara, Arden Bement, Richard Koubek, Bopaya Bidanda, Agostino Capponi, Seokcheon Lee, Mark R. Lehto, Andrew L. Liu, Omid Nohadani, Marcos Dantus, Peter W. Lorraine, David D. Notle, Robert W. Proctor, Harshad P. Sardesai, Leyuan Shi, Juan P. Wachs, Xi-Cheng Zhang
The purpose of this white paper is to review the key emerging innovations in laser and photonics systems, their design and integration, focusing on challenges and opportunities for solutions of societal grand challenges. Developments, their significance

Spectral line shapes investigation with Pound-Drever-Hall-locked frequency-stabilized cavity ring-down spectroscopy

October 23, 2013
Author(s)
A. Cygan, S. Wojtewicz, J. Domyslawska, Piotr Maslowski, Katarzyna E. Bielska, M. Piwinski, K. Stec, R.S. Trawinski, F Ozimek, C. Radzewicz, Hisashi Abe, T. Ido, Joseph T. Hodges, D Lisak, R. Ciurylo
A review of recent experiments involving a newly developed Pound-Drever-Hall-locked frequency-stabilized cavity ring-down spectroscopy (PDH-locked FS-CRDS) system is presented. By comparison to standard FS-CRDS, the PDH lock of the probe laser to the ring
