Light is projected onto a surface. The reflection creates an interference pattern.
2. Phase Shifting Applied
Multiple images are taken with slight shifts in phase.
3. Fourier Transform Processing
The system processes the signal using mathematical analysis.
4. Surface Reconstruction
Data is converted into a detailed surface map.
5. Final Output
You get accurate measurements of:
- Surface shape
- Irregularities
- Optical quality
