ABSTRACTA Fluorocarbon resin surface was selectively modified by irradiation with a ArF laser beam through a thin layer of NaAlO2, B(OH)3, or H2O solution to give a hydrophilic property. As a result, with low fluence, the surface was most effectively modified with the NaAlO2 solution among the three solutions. However, the contact angle in this case changed by 10 degrees as the fluence changed only 1mJ/cm2. When modifying a large area of the surface, high resolution displacement could not be achieved because the laser beam was not uniform in displacing functional groups. Thus, the laser fluence was successfully made uniform by homogenizing the laser beam; the functional groups were replaced on the fluorocarbon resin surface with high resolution, which was successfully modified to be hydrophilic by distributing the laser fluence uniformly.

AbstractMany common ocean sensor systems measure a localized space above a single sensor element. Single-point measurements give magnitude but not necessarily direction information. Expanding single sensor elements, such as used in salinity sensors, into arrays permits spatial distribution measurements and allows flux visualizations. Furthermore, applying microsystem technology to these macro sensor systems can yield imaging arrays with high-resolution spatial/temporal sensing functions. Extending such high spatial resolution imaging over large areas is a desirable feature for new “vision” modes on autonomous robotic systems and for deployable ocean sensor systems. The work described here explores the use of printed circuit board (PCB) technology for new sensing concepts and designs. In order to create rigid-conformal, large area imaging “camera” systems, we have merged flexible PCB substrates with rigid constructions from 3-D printing. This approach merges the 2-D flexible electronics world of printed circuits with the 3-D printed packaging world. Furthermore, employing architectures used by biology as a basis for our imaging systems, we explored naturally and biologically inspired designs, their relationships to visual imagining, and alternate mechanical systems of perception. Through the use of bio-inspiration, a framework is laid out to base further research on design for packaging of ocean sensors and arrays. Using 3-D printed exoskeleton's rigid form with flexible printed circuits, one can create systems that are both rigid and form-fitting with 3-D shape and enable new sensor systems for various ocean sensory applications.

Purpose. This paper presents the results of the first human trial on the correction of hyperopia using an erodible mask excimer laser delivery system coupled to an axicon. Methods. We treated 17 eyes of 17 patients (age range 34–62 years) for the correction of +3.21 ± 1.04 D (range +1.00 to +4.00 D). The hyperopic correction was made using an erodible mask inserted on the laser optical pathway, to produce a circular ablation measuring 6.5 mm in diameter. An axicon was then used to create a blend transition zone from 6.5 mm up to 9.4 mm in diameter. Eyes were evaluated at one, three and six months after surgery. Results. Reepithelization was always observed by the fifth postoperative day, despite the large area of deepithelization (diameter 9.5 mm). Mean refractive error one month after treatment was −2.44 ± 1.59 D (range 0.00 to −6.50 D). Five eyes (29.4%) had a best corrected visual acuity loss more than two to three lines; all eyes showed mild annular haze not involving the central part of the cornea. Six months after treatment, mean refractive error was −0.88 ± 0.99 D (range +0.50 to −3.00 D). Compared to preoperative status, 13 eyes (76.5%) showed an improvement in uncorrected distance visual acuity (1–8 lines), and 14 eyes (82.4%) showed an improvement in uncorrected vision at reading distance (3–7 lines). Two eyes (11.7%) showed a best corrected visual acuity loss of two of three lines. Conclusions. These preliminary results indicate this approach is effective in reducing hyperopia, while its predictability has still to be proved in a larger treatment group with longer follow-up. A cautious approach to this technique is still advisable, especially for higher hyperopic corrections, in view of the large best corrected visual acuity loss seen in two eyes at six months.
