Presented at ICALEO 2009
This paper presents a new method for the fabrication of smart cutting tools with embedded optical Fiber Bragg Grating (FBG) sensors. In-situ measurement of loads using smart tools during the machining process improves the productivity and precision and reduces the production time. In this regard, fiber gratings embedded in the macro-scale metallic structures of smart tools can increase the performance and efficiency of the tools. H...$28.00

Presented at ICALEO 2009
The present paper is concerned with improving the sensing performance of optical fiber Bragg gratings (FBG) through the design and fabrication of periodic metallic thin films around optical fibers for the realization of superstructure FBGs (SFBG). Periodic metallic layers are designed in such way that when the fiber is placed in structural or thermal fields, the index of refraction is selectively m...$28.00

Near field nanomanufacturing can break the diffraction limitation and generate features at nanoscale. However, current near field nanomanufacturing suffers from the low throughput and hinders its practical applications. In this paper, we are presenting a new approach of adopting a tip array and generate an array of features with nanoscale resolution. The nanodevices fabricated by this techniqu...$28.00
