Space applications require image sensors that are tolerant to the harsh radiation conditions outside the earth’s atmosphere. This paper reports about an ongoing optimization experiment for radiation tolerant 4T pixels. The experiment is conducted in a 0.18μm CMOS image sensor process and involves optimization of both the layout and the process technology. The purpose of the experiment is to min...

The objective of this project is to develop methods to incrementally model and detect changes in the shape or surface material properties of terrain. The model will be derived from range data (such as interferometric synthetic aperture radar (IFSAR) elevation data) and electrooptical (EO) and infrared (IR) imagery. The imagery can be either still images or video data, such as that obtained from...

In this paper biophysical bases and frontiers of complementary medicine are considered, and essential significance of its resonance microwave (MW)/ultralowfrequency (ULF) electromagnetic (EM)/ionic nature as well as the quantum-holographic "electrooptical" neural-network-like-function of the acupuncture system are pointed out, as supported by microwave resonance therapy (MRT) of the psychosomat...

The exoelectric e ect provides a linear coupling between electric polarization and orientational deformation in liquid crystals. It in uences many electrooptical phenomena and it is used in some bistable nematic devices. A statistical theory of dipole exoelectric polarization in biaxial nematic liquid crystals is used to calculate temperature dependence of order parameters, elastic constants, a...

Vertically aligned negative nematics are employed in high-end projection applications, where extremely high light fluxes are employed. Under these conditions, the UV photochemical stability of the material becomes an issue that must be included in the characterization process of such devices. Photochemical aging tests for vertically aligned microdisplay, however, must take into account the line...

Investigations on the nature of both linear and nonlinear electrooptic eeects in columnar mesophases of chiral discotic dibenzopy-rene and triphenylene derivatives and their mixtures are presented. We specially focus on the innuence of chirality on the switching process. INTRODUCTION Ferroelectricity in tilted smectic phases of chiral molecules was predicted to occur by R. B. Meyer et al. in 19...

A new class of liquid electro-optics based on electrowetting is able to replicate the high performance of solid geometrical optics. Scaled-down electrowetting optics can be arrayed in order to achieve a flat and large area form factor. Techniques for applying electrowetting devices to light valves and arrayed microprisms are reviewed. Electrowetting light valves (ELVs) reconfigure the geometry ...
