Phase Contrast and Differential Interference Contrast Microscopy

Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

Background:

Microscopic fringe projection profilometry (MFPP) is crucial for microscale industrial part inspection.
Scheimpflug multi-view imaging extends depth of field (DOF) but is challenged by lens distortion.
Lens distortion degrades measurement accuracy and hinders seamless multi-view data fusion.

Purpose of the Study:

To introduce a non-iterative distortion correction method for Scheimpflug multi-view MFPP.
To enhance the accuracy and efficiency of micro-scale 3D metrology.
To enable seamless fusion of data from multiple views in MFPP systems.

Main Methods:

Developed a non-iterative approach to directly remap camera and projector pixels using pre-calibrated parameters.
Calculated undistorted fringe positions by intersecting sight lines with a sub-pixel-interpolated Digital Micromirror Device (DMD) grid.
Eliminated the need for pattern reloading or iterative optimization in the distortion correction process.

Main Results:

Reduced root-mean-square error (RMSE) for 3D measurements of planes by 43.5% and spheres by 21.1% in a dual Scheimpflug camera system.
Demonstrated seamless multi-view fusion capabilities through reconstruction of a complex aircraft model.
Achieved a computationally efficient and accurate solution for micro-scale 3D metrology challenges.

Conclusions:

The proposed non-iterative distortion correction method significantly enhances MFPP accuracy.
The technique facilitates effective multi-view data fusion for complex microscale metrology.
This approach offers an efficient and precise solution for industrial micro-scale 3D inspection.
