Surface topography acquisition method for double-sided near-right-angle structured surfaces based on dual-probe wavelength scanning interferometry.

This paper proposes an approach to measure double-sided near-right-angle structured surfaces based on dual-probe wavelength scanning interferometry (DPWSI). The principle and mathematical model is discussed and the measurement system is calibrated with a combination of standard step-height samples for both probes vertical calibrations and a specially designed calibration artefact for building u...

A method for inspecting double-sided high-sloped structured surfaces based on dual-probe wavelength scanning interferometer

Double-sided high-sloped structured surfaces such as V-groove surfaces and Fresnel lenses are widely used in optical fibre positioning, retro-reflection, grating, light guiding and light concentration for solar power installation. Both the surface finish as well as the dimensions of the structured surfaces play important roles in the quality of the final products. Numerous efforts have been put...

Comparison of a Scanning Interferometric Profile Measurement Method and an Ultra-Precise Coordinate Measuring Machine

Comparative profile measurements of a test specimen with a diameter of 150 mm and a peak-to-valley height of 50 μm carried out by an ultra-precise coordinate measuring machine (Panasonic UA3P) and a highly accurate scanning interferometric multi-sensor instrument (ETMS) are presented. The instruments and their principles are described. Although the measurement principles of the instruments are ...

Su, Rong and Wang, Yuhang and Coupland, Jeremy and Leach, Richard K. (2017) On tilt and curvature dependent errors and the calibration of coherence

Although coherence scanning interferometry (CSI) is capable of measuring surface topography with sub-nanometre precision, it is well known that the performance of measuring instruments depends strongly on the local tilt and curvature of the sample surface. Based on 3D linear systems theory, however, a recent analysis of fringe generation in CSI provides a method to characterize the performance ...

In-process fast surface measurement using wavelength scanning interferometry

A wavelength scanning interferometry system for fast areal surface measurement of micro and nano-scale surfaces which is immune to environmental noise is introduced in this paper. It can be used for surface measurement of discontinuous surface profiles by producing phase shifts without any mechanical scanning process. White light spectral scanning interferometry, together with an acousto-optic ...
