Zusammenfassung Mit dem Kompetenzzentrum für Windenergie (CCW) hat die Physikalisch-Technische Bundesanstalt (PTB) eine Infrastruktur zur hochgenauen Messung großer dreidimensionaler Bauteile mit Abmaßen bis 5 m × 4 m × 2 m sowie großer Drehmomente bis 5 MN⋅m geschaffen. Die Drehmomenten-Normalmesseinrichtung ist bereits für die Erzeugung und Messung von Drehmomenten bis 20 MN⋅m ausgelegt. Zusätzlich verfügt das CCW über eine Einrichtung, mit der sich Wind-LIDAR-Systeme quantitativ erfassen lassen. Diese Messeinrichtungen mit ihren zugehörigen Messverfahren sind in ihrer Messgenauigkeit weltweit bisher unerreicht. Wie sich heute zeigt, zahlt es sich aus, dass die PTB bereits vor der Energiewende mit diesen Entwicklungen begonnen hat, um auf die bestehenden messtechnischen Herausforderungen Antworten auf die wirtschaftlichen, politischen und gesellschaftlichen Fragen zu geben. Alle drei Messverfahren werden in diesem Beitrag zusammenfassend angesprochen. Ausführliche Erläuterungen finden sich in weiteren Beiträgen dieser Ausgabe.

Abstract The increasing demand for micro- and nanofabrication and in parallel the increasing requirements on feature size and resolution is leading to an enormous growth in the field of multi-photon three-dimensional fabrication. To enable new and diverse investigations in this field and to enable high precision for nanofabrication on large areas, a high precision positioning system is combined with an ultra-short pulse laser system. The aim is a modular setup with constant adherence to the Abbe-comparator principle in order to achieve systematic improvements in the area of Direct Laser Writing. For a high-quality identification of the microstructures a measurement tool based on atomic force microscopy is used. To enable the fabrication of continuous micro- and nanostructures on large area, an extremely high positioning precision is used, where no further stitching methods are necessary. Therefore as base of the Direct Laser Writing system the nanopositioning and nanomeasuring machine (NMM-1) is used, which was developed at Technische Universität Ilmenau together with SIOS Meßtechnik GmbH, with a positioning volume of 25 mm × 25 mm × 5 mm and a positioning resolution in the sub-nanometer range. First investigations already confirmed that microfabrication with a Femtosecond Laser and the NMM-1 could be realized and showed the possibility of further developments in the field of Direct Laser Writing. Now the modular structure as a research platform is designed in such a way that the various extensions and measurement setups for large-scale investigations can always be implemented in a metrologically traceable manner. The presented work shows the development of a modular functional setup of an exposure system and NMM-1, which enables micro- and nanofabrication and an improvement in the structure size over large areas.
随着人们对微纳米加工的需求不断增加，以及对特征尺寸和分辨率要求的不断提高，多光子三维制造领域得到了巨大的发展。为了在这一领域进行新的和多样化的研究，并实现大面积纳米加工的高精度，高精度定位系统与超短脉冲激光系统相结合。目的是一个模块化的设置与不断坚持阿贝比较原则，以实现在直接激光书写领域的系统改进。为了获得高质量的显微结构鉴定，采用了基于原子力显微镜的测量工具。为了能够在大面积上制造连续的微纳米结构，使用了极高的定位精度，而不需要进一步的拼接方法。因此，采用Technische Universität Ilmenau与SIOS Meßtechnik GmbH联合开发的纳米定位和纳米测量机(NMM-1)作为直接激光书写系统的基础，定位体积为25 mm × 25 mm × 5 mm，定位分辨率在亚纳米范围内。初步的研究已经证实，用飞秒激光器和NMM-1进行微加工是可以实现的，并显示了在直接激光书写领域进一步发展的可能性。现在，模块化结构作为一个研究平台的设计方式是，各种扩展和大规模调查的测量设置可以始终以计量可追溯的方式实施。所提出的工作显示了曝光系统和NMM-1的模块化功能设置的发展，这使得微纳米加工和大面积结构尺寸的改进成为可能。

Abstract This paper presents a novel approach for accurately testing triangular waveform generators by leveraging the Ramp Vernier Test methodology commonly used for Analog-to-Digital Converters (ADCs). The proposed procedure enables efficient measurement of the nonlinearity of a triangular waveform using a low-cost data acquisition board. The key idea is to utilize the waveform generator under test to produce the stimulus signal for the data acquisition system’s testing. By analyzing the results of this test, the nonlinearity of the acquisition system can be determined and subsequently corrected. This approach effectively eliminates the influence of the acquisition system’s nonlinearity on the estimation of the nonlinearity of the waveform generator, ensuring accurate and reliable measurements.
