Greater than 80% transmission has been demonstrated for electrowetting light valves (ELVs). The ELV pixel structure consists of a backlit oil/water-on-dielectric electrowetting cell. Recent improvements in pixel design and oil formulation now allow for lower voltage and higher contrast operation. The ELVs are also video rate capable and unlimited in view angle.

Burst mode SAR’s such as ScanSAR or TOPSAR can achieve wide swath coverage in a single pass of the satellite at the cost of degraded cross-range resolution. In the bistatic configuration using a SAR satellite as illuminator of opportunity and a ground-based stationary receiver close to the imaged area, this coarse cross-range resolution can be improved in some favourable geometries by exploitin...

204 LLE Review, Volume 84 Introduction Measurements of shell integrity are very important for understanding and quantifying the performance degradation of spherical implosions in inertial confinement fusion (ICF).1 Such measurements are performed at the peak of compression of the implosion, when maximum density and temperature are achieved. At this time, the hot core and the inner surface of th...

We introduce a new approach to the detection and the classification of effects in video sequences. We deal with the effects such as cuts, fades, dissolves, and camera motions. A global motion compensation based on block matching and a measure of block mean intensities are used to detect all the effects. We determine the dominant motion vectors to detect the camera motions for each shot and obse...

Despite the popularity of financial compensation as a means for addressing trust violations, the question whether (more) money can indeed buy trust back remains largely unexplored. In the present research, we focus on the role of violation type and compensation size. The results of a scenario study and a laboratory experiment show that financial compensation can effectively promote the restorat...

An integrated polarized light guide was designed and fabricated for use as a liquid-crystal backlight with emphasis on uniformity of the light and conversion of p-polarized to s-polarized light. Two different micro-optical structures were fabricated both on the top and the bottom surfaces of the light guide. On the top surface, a subwavelength grating separates s-polarized and p-polarized light...

A compact light guide plate (LGP) with special designed microstructures and dual collimated light sources was proposed to achieve an adjustable viewing angle backlight for eco-display. The micro-prisms were utilized to guide the emitting rays toward normal viewing cones while a set of strip patterned diffuser toward wide viewing cones. The uniformity of spatial luminous can reach 91% / 87% at v...

We have developed a new technique for generating homogeneously distributed irregular dot patterns useful for optical devices and digital halftoning technologies. To introduce irregularity, we use elaborately designed sequences called low-discrepancy sequences instead of pseudorandom numbers. We also use a molecular-dynamics redistribution method to improve the distribution of dots. Our method c...
