An Integrated Optical-Holographic Chemical-Vapor Sensor
This thesis addresses the problem of chemical vapor detection by using an integrated opticalholographic interferometer for precision interrogation of a chemical transducer. A monolithic-prism interferometer, incorporating dynamic holography in conjunction with a “sniff-locked-loop” sampling scheme, achieves high sensitivity at high speed while mitigating the deleterious effects of environmental...
متن کاملOptical pH Sensor Based on Quinizarin for Alkaline pH Regions
The development of an optical pH sensor based on immobilization of quinizarin (1,4-dihydroxyanthraquinone) on a triacetylcellulose membrane was described. The resulting membrane exhibited fast color change from yellow to violet, while changing the pH in alkaline region. The immobilized quinizarin showed a broader dynamic range from (pH 9.4-11.4) with respect to free form (pH 8.8-10.4). The sens...
متن کاملOptical Head Design for 1 TB Optical Tape drive
A multi-channel Optical Head has been developed to be incorporated with an Optical Tape Drive that enables greater than 1TB capacity and greater than 25 MB/s data transfer rate on a 0.5 mil thick, 0.5 inch wide optical tape that fits in a 3480 style cartridge. The optical design has been optimized to perform at 532 nm with maximum through put in the write path. With use of a 0.6 NA objective le...
متن کاملSeparation of metallic and semiconducting single-walled carbon nanotube arrays by "scotch tape".
The dielectrophoretic (DEP) separation of metallic and semiconducting single-walled carbon nanotubes (SWNTs) has been investigated. DEP separation experiments were performed by following the previous reports and the modification of Raman spectra was confirmed. We then theoretically investigated the impact of the flow field on the dielectrophoretic separation. The electrothermal flow was found t...
متن کاملObservation of X-ray Emissions Resulting From Scotch Tape: Final Report
It has been shown that if ordinary scotch tape is unrolled in a vacuum, it will emit x-rays and visible light. The proposed experiment will investigate this property by building a suitable vacuum chamber and observing the x-rays from various tapes, unrolled at different speeds, and under different vacuum conditions. Introduction It has been known since 1953 [1] that scotch tape can emit x-rays ...
