摘要： The invention relates to multiplex addressing of a liquid crystal device comprising applying a strobe signal to one of a first plurality of electrodes of the device and a data signal to one of a second plurality of electrodes of the device. The strobe and data signals address a pixel of the device. The data signal comprises one of a SELECT data signal and a NON_SELECT which each have a duration and a discriminating duration which is no longer than the duration. During the discriminating duration the SELECT and NON_SELECT signals are different. The strobe signal comprises a first portion applied simultaneously with the discriminating duration of the data signal and a second portion applied after the discriminating duration of the data signal. By including a section at a larger voltage magnitude in the second portion of the strobe signal than is present in the first part of that signal, improved performance and addressing speed are obtainable. The Figure shows the four possible combinations of data signal over two addressing periods on the left hand side and a strobe signal in accordance with the invention at the top. The figure shows that SELECT resultant signals A and B closely match the ideal waveshape for fast change of state while the NON_SELECT resultant signals C and D give good discrimination.

摘要： A liquid crystal element includes two pieces of light-transmissive substrate (1,2) which respectively include signal electrodes (3) and scanning electrodes (5) arranged in stripe patterns, and a liquid crystal layer (10) formed by filling the space between the light-transmissive substrates with a ferroelectric liquid crystal. A conductive line (11) is provided between adjacent signal electrodes (3) and adjacent scanning electrodes (5) so that only the longitudinal side faces of the conductive line are in contact with the longitudinal side faces of the respective electrodes. Each electrode (3) and conductive lines (11) adjacent to the electrode form a hybrid electrode, and an insulating light-blocking member (13) is formed between adjacent hybrid electrodes. The conductive line includes a first layer (11a) in contact with the light-transmissive substrate, a second layer (11b) placed on the first layer, and a topmost third layer (11c). The first layer is made of a conductive material such as indium tin oxide and tantalum, which is highly adhesive to the light-transmissive substrate. This structure ensures the flatness of the conductive lines, and prevents peeled-off conductive lines. The invention also provides a method of fabricating such an electrode substrate.

摘要： An electro-optical detection system for detecting objects (12) embedded within a partially transmitting medium comprises means (20) to receive electro-magnetic radiation in two close spectral channels (28, 212): a signal channel (212) where the wavelength and bandwith of the signal channel are optimised to correspond to the peak of transmission of the medium and a reference channel (28) where the wavelength and bandwidth are selected to correspond to a spectral region where attenuation in the medium is high. The signal and reference channels are then subtracted (213) so as to remove the effect of reflected radiation from the signal channel (212). The signal is processed digitally (218) to provide an enhanced image of the field of view. In a particular arrangement for detecting objects underwater a CCD TV camera (20) is used with three separate CCD detector arrays providing concurrent red (R), green (G), blue (B) output signals. The green and blue signals are combined in an adjustable ratio to provide the image signal to match the prevailing conditions of the partially transmitting sea. A notch filter is employed to cut out light in a spectral band between the signal and reference channels.

摘要： A liquid crystal array device (10) comprises a liquid crystal material contained between two substrates (12, 20), a first and a second plurality of electrodes (16, 22) defining a plurality of pixels and driving circuitry (18, 26, 28) for applying a first signal (Strobe Voltage) in succession to the first plurality of electrodes and for applying a plurality of second signals (Data Voltage) to each of the second plurality of electrodes. Each second signal comprises one of at least a first waveform (a) and a second waveform (b) and the first waveform and the second waveform each comprise first and second signal levels. The first waveform (a) and the second waveform (b) further comprise at least one portion at a third signal level different from the first and second signal levels. This provides a limited difference in heating effect upon the array between a signal comprising a plurality of first waveforms (a, a, a, a etc.) and an alternating succession of first and second waveforms (a, b, a, b, a, b etc.).

摘要： A radar reflector comprises a pair of opposed colinear solid dielectric lens reflectors (10) and two corner reflectors (11) between to provide substantially uniform and high reflectivity in the plane of the reflector elements. Radar energy strikes the outer convex surface of a first converging lens element (12) of relatively high dielectric constant and is then transmitted through a second lens element (17) of material having a relatively lower dielectric constant to a reflecting metallic coating (18) on the outer convex surface of the second lens element (17). The surfaces of the two lens elements (13, 14, 18) are formed such that their respective radii of curvature decrease with distance from the axis of symmetry (15). The first lens (12) is preferably silica flour in a polyester resin with a dielectric constant substantially equal to 3.4 while the second lens element (17) is an expanded foam polystyrene with a dielectric constant substantially equal to 2. Preferably the corner reflectors (11) are trihedral reflectors.
