This paper presents a parametric analysis of the sense and avoid capability for an electrooptical system on unmanned aircraft. Our sensor analysis is based on simulated encounters from a new U.S. airspace encounter model that provides a comprehensive distribution of typical visual flight rule (VFR) aircraft behavior and encounter geometries. We assess the exchange between the sensor field-of-vi...

The sub-wavelength THz emission point on a nonlinear electrooptical crystal, used in broadband THz near-field emission microscopy, is computationally modeled as a radiating aperture of Gaussian intensity profile. This paper comprehensively studies the Gaussian aperture model in the THz near-field regime and validates the findings with dual-axis knife-edge experiments. Based on realistic paramet...

The electronic coupling between the photoactive proteins and semiconductors can be used for fabrication of a hybrid biosolid-state electrooptical devices. The robust cyanbacterial nanosized protein-chlorophyll complex photosystem I (PS I) can generate a photovoltage of 1 V with a quantum efficiency of ∼1 and can be used as a phototransistor gate. A functional dry-oriented junction was fabricate...

Nowadays, chemically synthesized proteins and peptides are attractive building blocks and have potential in many important applications as biomaterials. In this review, applications of biomaterials to thermotropic liquid crystals are discussed. The review covers the improvement of the performance of liquid crystal displays using liquid crystal physical gels consisting of a liquid crystal and am...

A series of liquid crystals have been synthesized and studied based upon mononuclear orthoplatinated rod-like heteroaromatic and 1,3-diketonate ligands. The liquid crystalline properties of these molecules were investigated using polarized light optical microscopy, differential scanning calorimetry, single crystal X-ray diffraction, and powder X-ray diffraction. Increasing the number of alkyl c...

We carried out a search for companions to B stars using the adaptive optics system of the Advanced ElectroOptical System 3.6 m telescope. We observed 70 B stars in the I band, finding 16 companions, 10 of which are newly discovered companions. For each system with a detected companion we give its measured astrometry and differential magnitude. We then put the observation in context of the syste...

Photo-aligned ferroelectric liquid crystal (FLC) display reveals a perfect alignment in case of asymmetric boundary conditions, when the competition in aligning action of two solid surfaces is avoided. In this case a stable uniform photo-alignment on one of the cell substrates spreads out to the other, which is prepared to sustain planar alignment with a degenerate azimuthal direction. In the p...
