摘要:
An optical disk 11 (sample) is laid on a sample moving unit 21 within a vacuum chamber 20. An electron beam radiating mechanism 30 radiates an electron beam to the optical disk 11 while moving the optical disk 11 at a constant speed. Electron detecting means 27 detects an electron from the optical disk 11. Thus, the track pitch is measured on the basis of a detected electron signal and a measured movement amount of the optical disk 11. Also, the electron beam radiating mechanism 30 is provided with a fast deflector 33 for averaging within a deflection area to measure the track pitch.

Die Erfindung beschreibt ein Verfahren zur schnellen, integralen Charakterisierung der strukturierten Innen- und/oder Außenoberfläche von Wärmetauscherrohren mittels der Radar-Doppler-Spektroskopie. Die aus den Frequenzspektren zu bestimmenden Meßgrößen: Flächenintegral A, Mittelwert m und Varianz S (bzw. Standardabweichung σ = S) korrelieren direkt mit den geometrischen Kenngrößen der Strukturmorphologie. Sie erlauben unmittelbar Rückschlüsse auf die Wärmeübertragungseigenschaften (Verdampfungs-/Kondensationsleistung) der jeweiligen Struktur, insbes. sind zur wärmetechnischen Kennzeichnung keine gebrauchsfertigen Rohrmuster erforderlich (Fig 1).
