    摘要: Disclosed is a fill-level measuring device for determining the fill level in a container. The device comprises: a radar module for determining a distance to the surface of the filling material; a 3D camera for capturing at least one region of the surface of the filling material; and an evaluation circuit that is designed to measure a maximum distance and a minimum distance from the captured distance values and to determine the fill level on the basis of the distance, providing that the distance is smaller than the maximum distance value and greater than the minimum distance value. As a result of the redundancy or the verification provided by the 3D camera of the distance calculated by the radar module, the fill-level measuring device according to the invention is therefore more reliable with regard to the miscalculation of an incorrect fill level.

    摘要: An inspection apparatus for adjusting a working height for a substrate for multiple target heights is disclosed. The inspection apparatus includes a radiation source configured to provide a radiation beam and a beam splitter configured to split the radiation beam into multiple beamlets that each reflect off a substrate. Each beamlet contains light of multiple wavelengths. The inspection apparatus includes multiple light reflecting components, wherein each light reflecting component is associated with one of the beamlets reflecting off the substrate and is configured to support a different target height for the substrate by detecting a height or a levelness of the substrate based on the beamlet reflecting off the substrate.

    摘要: A projection detecting apparatus according to the present invention is that for detecting a projection on a surface of a running metal object, and includes a transmission antenna for radiating electromagnetic waves; a reception antenna for receiving reflected electromagnetic waves; and a transmission and reception signal processing section for processing a transmission signal and a reception signal. The transmission antenna and the reception antenna have unidirectionality and the transmission antenna and the reception antenna are installed in such a way that the reception antenna does not catch electromagnetic waves which have been radiated by the transmission antenna and reflected on the surface of the metal object and the reception antenna catches electromagnetic waves alone which have been radiated by the transmission antenna and reflected on the projection.

    摘要: The invention relates to a method for the quantitative determination of surface properties, wherein a spatially resolved image of a surface to be analysed, which contains a large number of measured values, is recorded. In a first method step, the measured values are analysed in order to determine those surface areas which have a specific physical property. A result value of this physical property is then determined, wherein this result value is characteristic of the values of the physical property of all those surface areas of the image determined by analysing the image. According to the invention, in addition to the result value, a further value (B) characteristic of the surface is determined and this characteristic value is displayed together with the result value (I).

    摘要: A system and method for identifying an optimal landing energy of a probe current in a scanning electron microscope system. A probe current having a known landing energy is directed at a sample for producing a signal electron beam. The current of the signal electron beam is measured by directing the beam to a current detector for calculating a current yield, which is the ratio of the signal current to the probe current. The landing energy can then be changed for subsequent measurements of the signal current to identify the landing energy which produces a desired current yield. Once identified, the landing energy value can be used to produce a signal electron beam directed towards an imaging detector to generate topographic images of samples.

    摘要: A charged particle beam microprobe apparatus capable of accurately determining the three-dimensional structure of a surface is disclosed in which a detection system including at least a pair of detectors disposed symmetrically with respect to the optical axis of an charged particle beam generating instrument is used for obtaining an image signal from a surface scanned with a charged particle beam, the image signal obtained by difference detection in the detection system is compared with a pair of variable reference levels opposite in polarity to each other, to be converted into positive and negative rectangular wave signals, and information on whether the scanned surface slopes upward or downward when viewed from the detection system and information on the gradient of the scanned surface are obtained from the polarity and pulse width of each of the positive and negative rectangular wave signals, respectively, to determine the three-dimensional structure of the scanned surface. That is, the charged particle beam apparatus does not utilize a phenomenon that the coefficient of backscattered electrons is proportional to the angle of slope of a primary beam impinging surface, and hence can use secondary electron suitable for forming a high resolution scanned image.
