Abstract: Patterns are written on workpieces, such as, glass sheets and/or plastic sheets used in, for example, electronic display devices such as LCDs. The workpiece may be larger than about 1500 mm may be used. An optical writing head with a plurality of writing units may be used. The workpiece and the writing head may be moved relative to one another to provide oblique writing.

Abstract: Devices and methods for manufacturing displays, solar panels and other devices using larger size workpieces are provided. The workpiece is rolled into a cylinder, thereby reducing the physical size by a factor of 3 in one dimension. The stages on which the workpieces are rolled have a cylindrical shape, which allows a more robust and/or compact movement of the glass, reduced machine weight. The workpieces are relatively thin, more flexible, and are rolled onto a cylinder with a diameter of about 1 meter.

Abstract: The technology disclosed relates to a partially coherent illuminators. In particular, it relates to a partially coherent illuminator that directs laser radiation across multiple areas of an illumination pupil. In some circumstances, this reduces spatial and/or temporal coherence of the laser radiation. It must be used with a continuous laser to provide partially coherent illumination from a coherent laser. It can be combined with a workpiece tracker that effectively freezes the workpiece and extends the time that laser radiation can be applied to expose a pattern stamp on the workpiece or, it can be used with a stepper platform, without a tracker. A dynamically controllable aperture architecture is a by product of the technology disclosed.

Abstract: The technology disclosed relates to an illumination source including numerous laser diodes. In particular, it relates to extending the duty cycle and/or reducing the frequency of component replacement by detecting failure of one or more individual laser diodes and compensating for the failure, without replacing the laser diodes. The technology disclosed can be used in cases of catastrophic laser diode failure by changing the power of remaining laser diodes to restore illumination to the coherence function similar to the pre-failure illumination field. Particular aspects of the technology disclosed are described in the claims, specification and drawings.

Abstract: The present disclosure relates to phase-sensitive calibration of an SLM system. In particular, it relates to selecting among local calibrations when there is more than one calibration that satisfies a calibration intensity criteria. It utilizes information available before Fourier filtering, from non-zeroth order diffraction components to counter drift among alternative local calibrations.

Abstract: The present invention relates to a method for calibrating elements in a spatial light modulator (SLM) as a function of an applied element control signal. A plurality of elements are calibrated simultaneously. A beam of electromagnetic radiation is projected onto at least a part of the SLM. An image of said part of said SLM is formed on a device for measuring intensity of electromagnetic radiation. Element calibrating data is generated by using the intensity data as a function of the applied element control signal by either driving a sub-matrix comprising at least two elements out of said part of the SLM to a sequence of applied element control signals or by seeking out the control signal for each element which give the same predetermined intensity value on the device for measuring the intensity of electromagnetic radiation and stepping through N different predetermined intensity values. The invention also relates to an apparatus for patterning a workpiece having such a calibration method.

Abstract: A multi-carrier power amplifying arrangement has a number of amplifying devices, each of which includes a main amplifier and a linearizing device. Furthermore it includes a device signal for adding the adding output signals from the amplifying devices in phase, a device for detecting the average phase error of the amplified signals and for providing a compensating control signal. The compensating control signal is provided to each amplifying device at least to compensate for the average phase error.
