We present the conductometric behavior of a single atomic carbon nanostructure (graphene) that could be promising to infrared optoelectronic applications. A graphene nanomanipulation system with focused infrared laser source for optoelectronic property characterizations is implemented. The feasibility of mechanical and electrical probing manipulations on two-dimensional thin film nanostructures is studied. Using this system, we revealed the infrared optoelectronic properties of mono- and multilayer graphene. The obtained optoelectronic parameters are compared to the single- and multi-walled nanotubes. A graphene infrared sensor is prototyped by direct writing of electrodes using gold nanoink fountain-pen method and is analyzed by electrical probing. Results show that graphene could be a promising building block for thin film optoelectronic devices.

The localized heating produced by a tightly focused infrared laser leads to surface tension gradients at the interface of microfluidic drops, resulting in a net force on the drop whose origin and magnitude are the focus of this paper. First, by co-localization of the surfactant micelles with a fluorescent dye, we demonstrate that the heating alters their spatial distribution, driving the interface out of thermodynamic equilibrium. This soluto-capillary effect opposes and overcomes the purely thermal dependence of the surface tension, leading to anomalous Marangoni flows. This sets the interface into motion and creates recirculation rolls outside and inside the drop, which we measure using time-resolved micro-Particle Image Velocimetry. Second, the net force produced on the drop is measured to be in the range of a few hundred nN by using an original microfluidic design. This micro-dynanometer further shows that the magnitude of the heating, which is determined by the laser power and its absorption in the water, sets the magnitude of the net force on the drop. On the other hand, the dynamics of the force generation is determined by the time scale for heating which is independently measured to be τΘ = 4 ms. This time scale sets the maximum velocity that the drops can have and still be blocked, by requiring that the interface pass the laser spot in a time longer than τΘ. The maximum velocity is measured at Umax = 0.7 mm/s for our geometric conditions. Finally, a simple model is derived that describes the blocking force in a confined geometry as the result of the viscous stresses produced between the drop and the lateral walls.

This paper realized an inspection system of the cowl cross assembly which is an automotive part using single CCD camera. Edge is extracted by Sobel operator after improving image quality with homomorphic filter. The unnecessary segments and the unnecessary edge elements are removed from the obtained edge image by labeling. The accurate center of the merged segment can be estimated using RHT (Randomized Hough Transform). Existence of defect can be decided by comparing the CAD information of the cowl cross assembly with the estimated center position. Efficiency of the proposed method was proven by accurate inspection result for various target images at the poor environment such as the real industrial field

In this work, we present a new and semi-analytical method to investigate one dimensional Fibonacci-class photonic quasicrystals as an optical waveguide. Usually, the exact method for obtaining band diagram in these situations is very hard and the numerical methods are used. In this paper, we investigate the band structure characteristics of one-dimensional quasicrystals by using perturbation method. In this direction, the band diagram and field distribution of this structure are obtained.

We report on innovative application of microchannels, fabricated by femtosecond laser irradiation followed by chemical etching. This technique allows us to demonstrate a novel approach to the achievement of organic photonic devices, where the unique properties of a conjugated polymer in solution are exploited in a microfluidic configuration in order to produce an easy-to-integrate photonic device. Filling the microchannel with a diluted polyfluorene solution and by dispersing nanoparticles in the solution we are able to achieve random lasing in the microchannel.

For future short- and mid-range industrial applications, optical free-space communication systems are expected to play a major role. When moderate transmission rates (100 Mbps range) are required, optical wireless communications present a viable and promising technology supplemental to conventional radio wireless systems. Advanced approaches based on diversity techniques and adaptive signal processing show potential to achieve both high spatial coverage and high bit rates of more than 100 Mbps. Visible light communication systems using white phosphorescent LEDs present equally an interesting application potential, combining illumination with data transfer. When high data volumes (100 Gbps range) need to be transmitted, tailored optical data links provide a solution of choice. Exemplarily, a scalable (24 – 140 Gbps) optical data link is presented, developed for future implementation in maskless lithography systems. The link comprises a high-speed data buffer with synchronizable architecture and scalable throughput (N x 24 Gbps), an optical free space transmission solution, and, finally, a 45 channel low-noise optical receiver chip based on BiCMOS 0.6 µm technology.
在未来的中短期工业应用中，光自由空间通信系统有望发挥重要作用。当需要中等传输速率(100mbps范围)时，光无线通信是传统无线电无线系统的一种可行且有前途的补充技术。基于分集技术和自适应信号处理的先进方法显示出实现高空间覆盖和超过100 Mbps的高比特率的潜力。使用白光磷光led的可见光通信系统将照明与数据传输相结合，同样具有有趣的应用潜力。当需要传输大数据量(100gbps范围)时，定制的光数据链路提供了一个选择的解决方案。例如，提出了一种可扩展的(24 - 140 Gbps)光数据链路，为将来在无掩模光刻系统中实现而开发。该链路包括具有可同步架构和可扩展吞吐量(N x 24 Gbps)的高速数据缓冲器，光自由空间传输解决方案，以及基于BiCMOS 0.6µm技术的45通道低噪声光接收器芯片。

This paper deals with an application of a small mobile device, “AZARASHI (seal) Mechanism” with three degrees of freedom (DOFs) to a micromanipulation device. AZARASHI mechanism has a smaller number of controlled devices than the inchworm-like device. The small device with multiple DOFs can be built by combining such mechanism. A micromanipulation device consists of an L-shaped device for the x-, y- and θ-motions, and one-DOF device in the z-motion. By the visual feedback, a glass bead is placed automatically. In order to trap a glass bead with a diameter of 60–70 µm, the air was gently sucked through the glass capillary. Then the bead is trapped and placed after moving the stage. Finally, the bead is placed. The performance of the manipulation device was measured. Positioning accuracy of the stage was within 1 pixel. However, a process of the bead release often disturbed the total accuracy.

Thin film reflectometry is a common way to monitor film thicknesses in numerous processes. Semiconductor and optics producing industries, e.g., require film thickness observation. Spectral reflectometry interrogation is one of several methods, which can be assessed by various algorithms depending on resolution and measuring range demands. Incident angle is a crucial parameter to these interrogation methods. Light, under different incident angles, produces different spectral reflectivity functions. These are integrated by a detector, in this case a spectrograph. Therefore, one needs to minimize the range of incident angles onto the measured object in order to increase the resolution of film thickness. Lateral resolution may also be a crucial parameter in some processes. Lateral resolution is a function of the range of incident angle, it increases with increasing angle range. These two crucial facts result in an estimate of measuring error introduced by the angle range under a given maximal lateral resolution. A measuring setup for a range of incident angle measurements is presented, as well as an example interrogation of a thin film under different incident angles.

A miniaturized and electromagnetically driven FR4 based moving platform is developed for Fourier Transform spectrometer applications. Both Michelson interferometer and Lamellar Grating interferometer configurations are demonstrated. ±500 µm translational motion (corresponding to 5 cm−1 spectral resolution) is demonstrated with the moving platform. Two methods are proposed and partially demonstrated for pure translational motion: (1) integrated control system using a quad photo detector feedback and (2) corner cube retroreflector. The fundamental advantages and the limits of the lamellar grating interferometers are also discussed.

Information fusion approaches are more and more used in complex applications in which there is a real need to take into account several kinds of information simultaneously. Fusion systems become complex because they involve all the information treatment chain steps (from the extraction to the decision). A global evaluation of the fused result does not allow the end-users to adjust the numerous parameters and to efficiency interact with the system. This paper proposes a local approach to evaluate the mission completeness of each subpart of the fusion systems. For this, the main mission of each subpart needs to be well formulated and then, a mission achievement measurement will allow to quantify the performance of the subpart according to its objective and independently to the method used inside the subparts. The proposed measurement is based on an histograms comparison and the approach is then illustrated on a real cooperative fusion system devoted to 3D tomographic image interpretation.
