Application of Stereo Imaging to Atomic Force Microscopy
(2002-01)
Metrological data from sample surfaces can be obtained by using a variety of profilometry methods. Atomic Force Microscopy (AFM), which relies on contact inter-atomic forces to extract topographical images of a sample, ...
Modeling of Piezoelectric Tube Actuators
(2004-01)
A new dynamic model is presented for piezoelectric tube actuators commonly used in high-precision instruments. The model captures coupling between motions in all three axes such as bending motion due to a supposedly pure ...
On Dual Actuation in Atomic Force Microscopes
(2004-01)
In this paper, the problem of dual actuation in the atomic force microscope (AFM) is analyzed. The use of two actuators to balance the trade-off between bandwidth, range, and precision has been recently extended to ...
Imaging at the Nano-scale: State of the Art and Advanced Techniques
(2003-01)
Surface characteristics such as topography and critical dimensions serve as important indicators of product quality and manufacturing process performance especially at the micrometer and the nanometer scales. This paper ...
Review of bio-particle manipulation using dielectrophoresis
(2005-01)
During the last decade, large and costly instruments are being replaced by system based on microfluidic devices. Microfluidic devices hold the promise of combining a small analytical laboratory onto a chip-sized substrate ...
Facilitating Mechanical Design with Augmented Reality
(2005-01)
By enhancing a real scene with computer generated objects, Augmented Reality (AR), has proven itself as a valuable Human-Computer Interface (HCI) in numerous application areas such as medical, military, entertainment and ...
An Application of Augmented Reality (AR) in the Teaching of an Arc Welding Robot
(2005-01)
Augmented Reality (AR) is an emerging technology that utilizes computer vision methods to overlay virtual objects onto the real world scene so as to make them appear to co-exist with the real objects. Its main objective ...
Assembly Design and Evaluation in an Augmented Reality Environment
(2005-01)
The technologies and methodologies of assembly design and evaluation in the early design stage are highly significant to product development. This paper looks at a promising technology to mix real components (e.g. physical ...
Generation of Dielectrophoretic Force under Uniform Electric Field
(2006-01)
Effective dipole moment method has been widely accepted as the de facto technique in predicting the dielectrophoretic force due to the non-uniform electric field. In this method, a finite-particle is modeled as an equivalent ...
Atomic Force Microscope: Modeling, Simulations, and Experiments
(2002-01)
The quality of atomic force microscope (AFM) data strongly depends on scan and controller parameters. Data artifacts can result from poor dynamic response of the instrument. In order to achieve reliable data, dynamic ...
