Optically Investigating Flaws/Contamination TRIZ Cases

Spectral analysis checks preforms between production and forming, enabling feedback that improves quality control and reduces defects.

This examination approach separates interfering drive-element waveforms from overlapping light spots and aligns results with layout images.

Multiple terahertz transmission units and optical spacing create parallel light for uniform imaging and improved signal-to-noise.

Differential interference inspection adapts shear to correct phase shifts and expand height range without sacrificing accuracy.

Magnetic focus-direction drive keeps sloped samples within the focal range.

Ultraviolet excitation and separate wavelength filters capture magnetic blemishes and visible defects in one inspection setup.

A reflective surface scans multiple conjugate planes to locate internal optical defects and guide targeted cleaning or replacement.

Continuous angle control creates uniform brightness for clearer detection of transparent and elongated foreign matter in liquid containers.

Inspect each plastic preform, assign it to its production unit, and adjust production parameters through closed-loop control.

Pre-process data augments sparse references for faster semiconductor metrology.

A calibrated diffraction grating selects target wavelengths, helping wafer inspection address resolution limits in scaled chips.

A tilted optical path and telecentric aperture improve circular workpiece edge imaging by limiting distortion and halo artifacts.

A perpendicular elongated light spot improves dielectric fluorescence signals for accurate metal-layer pattern inspection.

Angled reflector planes distribute back illumination evenly across biological growth plates.
