Abstract: A system, method, and computer readable medium for increasing an upstream optical coding gain in a passive optical network (PON). In an exemplary embodiment of the invention, the system may include a memory structured to store Optical Network Terminator (ONT) burst timing values, and provide a previous burst timing value of the burst timing values to a translator. Further, an upstream burst grant timing scheduler may provide a scheduled timing value to the translator, wherein the translator may be structured to translate the previous burst timing value to a new expected timing value per an ONT upstream burst in association with the scheduled timing value. Also, a delimiter match and search block may be structured to use the new expected timing value to check a bit stream for a delimiter pattern match. An alarm counter may be provided in the system that is structured to provide an alarm when the delimiter pattern match is not found.

Abstract: A document readout device reads out a document by forming an image of a linear area of the document on an unmagnification sensor through an image-forming optical system. The document readout device has a roof mirror array, a lens array, an optical-path separator, one or two mirror members, a housing, an unmagnification sensor, and one or two line illuminating devices. The housing has a pair of slits, one of which is covered by the unmagnification sensor, with the other slit being positioned for introducing light into the housing. The roof mirror array, the lens array, the optical-path separator, and the mirror member or members are retained in the housing in certain mutual positional relationship. The unmagnification sensor and the line illuminating unit or units are integrally mounted on the housing. The roof mirror array, the lens array, and the optical-path separator jointly constitute the image-forming optical system. An image-forming light ray from the image-forming optical system is guided by the mirror member or members toward the unmagnification sensor.

Abstract: An imaging system employing an apparatus for evenly illuminating objects to be scanned. The apparatus includes first and second elliptical cylindrical sections which comprise an elliptical cylindrical mirror having first and second focal lines. A linear-type lamp is located at the first focal line and the scanning line of the imaging system is located at the second focal line. First and second planar mirrors are positioned in parallel relationship to each other at the top and bottom of the scanning line, and a non-reflecting surface on the second elliptical cylindrical section combines with the first elliptical section to provide an even distribution of light at the scanning line. The optical axis of the imaging system passes between the first and second elliptical cylindrical sections.

Abstract: For forming an array or series of elementary beams of charged particles, a beam exposure device includes a mirror system having a matrix of sub-mirrors. Using such a composite mirror, a multiple beam image is formed in a location which deviates from the position of the cross-over of principal rays of the elementary beams. Consequently, the elementary beams, which may alternatively be ion beams, can be separated modulated and controlled. For suitable imaging, such as the writing of patterns for a micro-electronic circuit element, the images and the cross-over of the principal rays of the elementary beams are combined. For this purpose, use is made of a second mirror whose sub-mirrors have an optical effect which opposes that of the first mirror.

Abstract: Disclosed are systems and methods for generating a beam of charged particles, such as an ion beam. Such a system may comprise an interaction chamber configured to support a target, one or more electromagnetic radiation sources, a sensor, and at least one processor. The one or more electromagnetic radiation sources may be configured to provide a probe beam at a first energy for determining orientation data of the target and a particle-generating beam at a second energy, which is greater than the first energy, for producing a beam of charged particles. The processor may be configured to receive feedback information from the sensor and to cause a change in a relative orientation between the particle-generating beam and the target.

Abstract: A method of separating charged particles using an analyzer is provided, the method comprising: causing a beam of charged particles to fly through the analyzer and undergo within the analyzer at least one full oscillation in the direction of an analyzer axis (z) of the analyzer whilst orbiting about the axis (z) along a main flight path; constraining the arcuate divergence of the beam as it flies through the analyzer; and separating the charged particles according to their flight time. An analyzer for performing the method is also provided. At least one arcuate focusing lens is preferably used to constrain the divergence, which may comprise a pair of opposed electrodes located either side of the beam. An array of arcuate focusing lenses may be used which are located at substantially the same z coordinate, the arcuate focusing lenses in the array being spaced apart in the arcuate direction and the array extending at least partially around the z axis, thereby constraining the arcuate divergence of the beam a plurality of times as it flies through the analyzer.

Abstract: With a multi-beam type charged particle beam apparatus, and a projection charged particle beam apparatus, in the case of off-axial aberration corrector, there is the need for preparing a multitude of multipoles, and power supply sources in numbers corresponding to the number of the multipoles need be prepared. In order to solve this problem as described, a charged particle beam apparatus is provided with at least one aberration corrector wherein the number of the multipoles required in the past is decreased by about a half by disposing an electrostatic mirror in an electron optical system.
