82. Collinear Optical Coherence and Confocal Fluorescence Microscopies for Tissue Engineering
Topic: Optical Metrology
Published: 1/1/2003
Authors: Joy P Dunkers, Marcus T Cicerone, N. R. Washburn
Abstract: We have combined confocal optical coherence (OCM) and confocal fluorescence (CFM) microscopies to gather simultaneous structural and functional information on tissue engineered products in a registered fashion. In this work, we present the design an ...

83. Applications of Optical Coherence Tomography to the Study of Polymer Matrix Composites
Topic: Optical Metrology
Published: 1/1/2002
Author: Joy P Dunkers
Abstract: The use of optical coherence tomography (OCT) to study polymer matrix composites (PMCS) is very recent. So recent, in fact, that the full potential and limitations of this technique have yet to be studied completely since PMCS are a large and varied ...

84. Comparison of Optical Coherence Tomography, X-Ray Computed Tomography, and Confocal Microscopy Results From an Impact Damaged Epoxy/E-Glass Composite
Topic: Optical Metrology
Published: 1/1/2002
Authors: Joy P Dunkers, D P Sanders, Donald Lee Hunston, M J Everett, William H. Green
Abstract: Optical coherence tomography (OCT) is an emerging technique for imaging of synthetic materials. OCT is attractive because of the combination of its high sensitivity (>90 dB), high resolution ((10-20) mm), and low cost (~$75 k). The value of any new ...

85. Non-Destructive Characterization of the Morphology of a Polymer Co-Extruded Scaffold Using Optical Coherence Tomography
Topic: Optical Metrology
Published: 12/19/2001
Authors: Joy P Dunkers, N Washburn, Carl GEORGE Simon Jr, Alamgir Karim, Eric J. Amis
Abstract: It is generally understood that a complex interaction of many variables controls the success of cell infiltration, proliferation, and differentiation within a tissue scaffold. One parameter that has a large influence on the development of functionin ...

86. The Prediction of Permeability for an Epoxy/E-Glass Composite Using Optical Coherence Tomographic Images
Topic: Optical Metrology
Published: 12/1/2001
Authors: Joy P Dunkers, Frederick R Phelan Jr, C G Zimba, Kathleen M. Flynn, D P Sanders, R C Peterson, Richard~undefined~undefined~undefined~undefined~undefined Parnas
Abstract: Knowledge of the permeability tensor in liquid composite molding is important for process optimization. Unfortunately, experimental determination of permeability is difficult and time consuming. A rapid, non-destructive technique called optical coh ...

87. Imaging of Multi-Fiber, Micro-Mechanical Testing Specimens Using Optical Coherence Tomography
Topic: Optical Metrology
Published: 2/1/2001
Authors: Joy P Dunkers, Gale Antrus Holmes, Walter G McDonough
Abstract: In this initial work, we interfaced a micro-mechanical testing stage with the optical coherence tomography (OCT) instrument. We then demonstrated the feasibility of this approach by comparing OCT images of single and multi-fiber sample to optical mic ...

88. The Application of Optical Coherence Tomography to Problems in Polymer Matrix Composites
Topic: Optical Metrology
Published: 1/1/2001
Authors: Joy P Dunkers, Frederick R Phelan Jr, D P Sanders, M J Everett, William H. Green, Donald Lee Hunston, Richard~undefined~undefined~undefined~undefined~undefined Parnas
Abstract: The Composites Group at the National Institute of Standards and Technology has found optical coherence tomography (OCT) to be a powerful tool for non-destructive characterization of polymer matrix composites. Composites often exhibit superior proper ...

89. Imaging of Composite Defects and Damage Using Optical Coherence Tomography
Topic: Optical Metrology
Published: 5/1/2000
Authors: Joy P Dunkers, M J Everett, D P Sanders, Donald Lee Hunston
Abstract: The Composites Group at the National Institute of Standards and Technology has found optical coherence tomography (OCT) to be a powerful tool for non-destructive characterization of polymer matrix composites. Composites can be made more cost competi ...

90. Imaging of Impact Damage in Composites Using Optical Coherence Tomography
Topic: Optical Metrology
Published: 2/1/2000
Authors: Joy P Dunkers, D P Sanders, Donald Lee Hunston, M J Everett
Abstract: Resistance to impact damage is extremely important for most composites. Such damage can initiate delamination, one of the most common failure modes in composites.. Because this is such an important failure mode, many studies have tried to develop ma ...
