The applications of windowed Fourier fringe analysis in the past decade are reviewed.
Because fringe patterns from different optical measurement systems are similar, the …

In white light scanning interferometry (WLSI), the accuracy of profile measurement achieved
with the conventional zero optical path difference (ZOPD) position locating method is closely …

Based on generalized cross-correlation time delay estimation (GCTDE), a new white light
scanning interferometry (WLSI) method is proposed, in which the profile information usually …

消除综合孔径望远镜子孔径之间的相对光程差是实现高分辨率干涉成像的前提条件,
条纹检测法是一种检测相对光程差的有效办法. 因子孔径的空间位置排布使干涉条纹具有一定的 …

Accurate measurement of soap film thickness distribution is a difficult and challenging task.
In this paper, dynamic thickness distributions of a soap film were measured and visualized …

Phase-contrast imaging (PCI) is a modality of medical x-ray imaging that can solve one of
the main limitations with conventional attenuation-based imaging: the imaging of materials …

Energy consumption has been steadily increasing over the past years and many studies
have been done on possible future trends. Most studies agree that this increase of energy …

Fringe test is the method which can detect the relative optical path difference in optical
synthetic aperture telescope array. To get to the interference fringes, the two beams of light …

Chromium carbon nitride (CrCN) hard films own high hardness, lower friction coefficient,
higher wear and corrosion resistance. Investigations on the surface roughness of CrCN hard …
