Atomic Force Microscopy

Atomic Force Microscopy

Atomic force microscopy (AFM) is a type of scanning probe microscopy that can analyze topographic details of various specimens like ceramics, glass, polymers, and biological samples. AFM offers over 1000 times more resolution than the optical imaging system. Images generated from AFM are three-dimensional surface profiles, offering an advantage over the flat, two-dimensional images from other imaging techniques.
The AFM Probe
The probe is regarded as the heart of any AFM setup and comprises the...

Background:

Fringe projection profilometry is a key technique for 3D surface measurement.
Traditional methods struggle with objects featuring large discontinuities.
Phase unwrapping can be complex and error-prone.

Purpose of the Study:

To introduce an alternative multi-frequency fringe projection profilometry method using wavelet transforms (WTs).
To enable accurate 3D profiling of objects with significant discontinuities.
To enhance measurement accuracy and reliability in 3D surface reconstruction.

Main Methods:

Projecting fringe patterns with multiple frequencies onto an object.
Digitally recording reflected fringe patterns.
Calculating phase information using wavelet transform ridges.
Applying a peak searching algorithm to determine object height from multi-frequency phase data.

Main Results:

Successfully profiled objects with large discontinuities.
Achieved height profiles with lower noise levels.
Demonstrated higher measurement accuracy compared to existing methods.
The proposed WT-based method offers greater reliability.

Conclusions:

Wavelet transforms provide an effective alternative for multi-frequency fringe projection profilometry.
The novel approach overcomes limitations of traditional phase unwrapping for discontinuous surfaces.
This technique enhances the accuracy, reliability, and robustness of 3D surface profiling.
