Laser Beam Hazard for flight personnel
Lasers can produce a beam of light of such intensity that permanent damage to human tissue, in particular the retina of the eye, can be caused instantaneously, even at distances of over 10 km. At lower intensities, laser beams can seriously affect visual performance without causing physical damage to the eyes; causing transient damage or causing sensation and loss of focus. Laser illumination o...
متن کاملLaser processing of polymer thin films for chemical sensor applications
Contemporary and next-generation commercial and defense-related platforms offer countless applications for thin-film polymer coatings, including the areas of microelectronics, optoelectronics, and miniature chemical and biological sensors. In many cases, the compositional and structural complexity, and the anisotropy of the material properties preclude the processing of many of these polymers b...
متن کاملLaser-based processing of polymer nanocomposites for chemical sensing applications
Pulsed laser deposition ~PLD! has been used to fabricate polymer/carbon nanocomposite thin films for use in chemical sensors ~chemiresistors!. Ethylene vinyl acetate copolymer ~EVA! films ~undoped and 20% carbon by weight! were deposited using an ArF excimer laser ~193 nm! at fluences between 150 and 300 mJ/cm. The structure and morphology of the deposited films were characterized using Fourier...
متن کاملA nanoscale metal alkoxide/oxide adhesion layer enables spatially controlled metallization of polymer surfaces.
Seeding polymer substrates for the attachment and growth of metallic contacts is an important problem in modern microcircuit fabrication. A new method to effect such polymer metallization is described in which the polymer is first treated with vapor of zirconium or titanium tetra-tert-butoxide and then thermalyzed to give several monolayers of zirconium or titanium oxides that are attached to t...
متن کاملMicroscale patterning of thermoplastic polymer surfaces by selective solvent swelling.
A new method for the fabrication of microscale features in thermoplastic substrates is presented. Unlike traditional thermoplastic microfabrication techniques, in which bulk polymer is displaced from the substrate by machining or embossing, a unique process termed orogenic microfabrication has been developed in which selected regions of a thermoplastic surface are raised from the substrate by a...
