    Abstract: Optical performance monitoring device for monitoring and analyzing an optical signal has a periodically movable reflective mirror to receive an input optical beam and to cyclically nullscannull (deflect) the beam in a one-dimensional direction. The deflected beam at a varying deflection angle is directed to a linear variable filter (LVF) that passes a selected wavelength channel of the deflected beam in dependence upon the deflection angle. The selected channel is then passed to a photodetector via a focusing lens, typically a cylindrical lens. The device is durable, tunable, offers low loss, good wavelength registrability and spectral resolution.

    Abstract: A field emission electron source includes: a field emission array portion composed of an insulation layer with a plurality of apertures, which is formed on a substrate, an extraction electrode formed on the insulation layer, and a plurality of cathodes formed respectively on the substrate in the plurality of apertures; a cathode base for fixing the field emission array portion; and an electron lens portion composed of a plurality of electrode members having a function of accelerating and converging an electron beam emitted from the field emission array portion. An emission axis of the electron beam emitted from the field emission array portion has a predetermined angle with respect to an optical axis of the electron lens portion. Thus, the field emission array portion can be protected from impact caused by ions generated in the electron lens portion, thereby improving the life of a field emission electron source.

    Abstract: A scanning device for measuring the distance between the scanning device and a plurality of surface points on a target object. The scanning device sweeps a laser beam and a line scan camera in synchronization up and down the surface of the target object. The line scan camera monitors the impact point of the laser beam upon the target object within its field of view. By knowing the position of the impact point within the camera's field of view, trigonometric principles can be applied to accurately calculate the distance to the impact point.

    Abstract: An apparatus for selecting and detecting at least one spectral region of a spectrally spread light beam, preferably in the beam path of a confocal scanning microscope, the spread light beam being focussable in a focal line, is characterized, for non-overlapping detection of the spectrally spread light beam of the selected spectral regions in the context of an increased number of detectors and an error-tolerant arrangement, in that there is arranged in the spread light beam an optical component which reflects and/or refracts the light beam to a detector and whose optically effective region becomes smaller or larger along the surface, so that by orientation of the component with respect to the focal line and the resulting superposition of the focal line and surface, the spectral region arriving at the detector is definable.
