In this paper, we have investigated the characteristics of polymer inkjet printing and fabricated OLED(organic light emitting diode) display using inkjet printing technology. To control the wetting condition of the droplet to the substrate, UV/ozone treatment technique is used. To make the repeated pixels on a substrate, precise vision alignment and multi-layer printing is used. With the successive printing of PEDOT/PSS as a hole injection layer and MEH-PPV as a light emitting layer, we have successfully fabricated an OLED and demonstrated basic working of OLED.

We successfully develop a defect inspection method based on a robust method for matching the distance between points in three dimensions. The three-dimensional distance data of an object is measured by means of a laser range finder. The data is compared with the measured data of a high-quality item. Then, we examine the differences between two sets of data in order to detect defects in the target object. The three-dimensional distance data is matched with high robustness by using the proposed method. Furthermore, we attach labels to sets of points corresponding to a detected defect. By performing an experiment with real data, we show that a high-quality object and a defect object can be distinguished on the basis of the features of each label.

We present a new two-axis spiral-shaped micromirror manipulator developed for free space optical switching. The actuator is an electrostatic actuator, comprised of two different parts, which are fabricated using conventional surface micromachining processes and then assembled. In spite of the conventional monolithic self-assembling design approaches, these two parts are fabricated on two different chips and assembled using a spatial-mechanical approach from point of view of a simple MEMS-manufacturing process of each part. Making as one MEMS device becomes a lot of number of processes. Because a fixed place of the screw beam from the mirror device is at the position where only the height of a lower micro pyramid is low compared with the height of a central point. The design utilizes the increased flexibility of the spiral shaped electrode and zipping effect technique in order to increase the maximum tilt angle. The footprint of the assembled device is 600µm×600µm and height of the micro pyramid is 200µm.The switch was simulated using an energy concept and electromechanical coupled model. Its performance was measured statically using a reflection measurement approach. A continuous tilt actuation of 17 degree has been achieved with actuation voltage of 235 volts.

The combination of microfluidic systems with laser optical manipulation of suspended objects extends the range of possible investigations in lab-on-chip environments. As an example, mechanical properties of cells can be measured with a specific dual-beam laser trap called the optical stretcher on a single cell basis. The combination of high power laser beams in excess of 1W into a microfluidic environment with high spatial accuracy presents considerable challenges. Here we discuss three alternatives to achieve this goal: a simple glass-capillary setup with only one flow channel, a more elaborate optofluidic chip made of Polydimethylsiloxane (PDMS) for rapid prototyping, and a monolithic glass chip for high durability, damage threshold and optical clarity. Advantages and disadvantage are being discussed. Such microfluidic optical stretcher setups open new possibilities for label-free characterization of cells with biotechnological applications.

Stabilization of images is required for many applications, these include target identification and tracking. Many methods of performing this stabilization exist, primarily classifiable as either software techniques or mechanical stabilization using external information such as an inertial reference system or geo-pointing system. The aim of this work is to investigate the feasibility of using only photogrammetric data obtained from a bow-mounted narrow field of view camera to mechanically stabilize the resultant image in rough sea conditions. This will allow the exclusion of inertial measurement equipment with its accuracy/expense trade off, yet still be able to stabilize the image in the presence of sea surge that places the target outside of the camera's nominal field of view. The experimental results obtained using a 3 axis ship motion simulator showed a 20dB and 30dB attenuation for roll and pitch respectively.

Lab-on-a-chips (LOCs) are becoming one of the most powerful tools of analytical chemistry, with a broad application in life sciences, biotechnology and drug development. They incorporate in a single substrate the functions of a biological laboratory (i.e. microfluidic channels, reservoirs, valves, pumps and sensors). Their main advantages include the possibility of working with small sample quantities (from nano- to picoliters), high sensitivity, speed of analysis and the possibility of measurement automation and standardization. Direct on-chip integration of photonic devices for detection of biomolecules flowing in the microchannels is one of the main objectives of current research in this field, which becomes particularly challenging in case of analytes that cannot be chemically labeled. In fact in this case an interferometric detection is often needed and optical devices, such as interferometers, have to be integrated. Ultrafast laser writing of waveguides in glasses proves to be a very flexible, simple and well suited method also for this kind of applications. As a post-processing technique it doesn't affect the fabrication of the fluidic part and its unique three-dimensional capabilities allow realization of devices with complex design. In this work we report on the use of femtosecond laser pulses to fabricate a Mach-Zehnder interferometer, integrated with a microfluidic channel; this provides label-free sensing, by means of refractive index measurements, of samples flowing in the microchannel.

An In this paper a multi channel narrow band DWDM filter based on aperiodic Thue-Morse (TM) multilayer structure is proposed. We study the transmission spectra of light propagation through these structures. Our numerical simulation shows an ultra high efficiency for this filter so that the total transmission of filter output channels up to 100% and the range of output wavelength is 1550 nm which is suitable for DWDM communication systems. By studying the effects of parameters of aperiodic Thue-Morse structure, we realized that with varying the parameters such as number of layers, the distance between layers, the refractive index of layers, and so etc., we can accomplish a suitable DWDM filter and the structure properties are changeable with them. For example, by increasing the distance between each layer, the bandwidth of output channels less than 1nm is obtained. The main advantage of Thue-Morse structure is the selectable layer numbers of it, that in our designed structure, we generalized the base structure and choose TM(3,2) that means m=3 and n=2 in BmAn.

A novel 2 Degree-of-Freedom (DOF) micro-electro-mechanical systems (MEMS) mirror with sidewall electrodes is presented. The paper analyzes the effects of the serpentine torsion bar width, and bottom electrodes and sidewall electrodes on the performance of the mirror. A new fabrication process based on silicon-on-insulator (SOI) wafer and a high aspect-ratio shadow mask is presented. In comparison to the previous fabrication process and the Optical iMEMS process, the presented process is novel, simple and easy to be realized. Static and dynamic experiments indicate MEMS mirror with sidewall electrodes can realize the large scanning angle under low drive voltage. This mirror is well-suited for application where large linear angular scan at a low driving voltage is required.

In this work, we study the effects of a CCD camera binning option, which increases camera frame rate throughput at the expense of loosing spatial resolution, on the Particle Image Velocimetry measurements. The camera frame rate defines upper bound on a speed of a flow a PIV system can measure. We have carried our experiments on the real images of the 1 µm size fluorescence polystyrene microparticles placed onto a thick quarts glass plate and illuminated with the high-power LED. The in-plane images were captured at various CCD binning factors and the distances between particles were calculated using cross-correlation analysis with a sub-pixel interpolation scheme based on the Gaussian regression. As a result of this study, we show that despite the decrease in the spatial resolution, the advantages of the pixel binning, such as increase in sensitivity and the total full frame rate, can be useful for LED illuminated PIV measurements, especially in laminar fluid flows.
