Solution Overview
Problem
Existing surface registration methods lack the capability for qualitative analysis of surface composition and characteristics, relying on limited interpretations of brightness values and assumptions, which restricts the derivation of detailed information about internal structures and compositions.

Incorporating spectral probing during surface scanning using additional laser sources and spectrometers, such as Fourier transform spectrometers, to analyze radiation in multiple spectral ranges, enabling the identification of material properties and changes beyond simple light-dark evaluations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If spectral probing is added to surface scanning, then qualitative analysis capability is improved, but device complexity increases
Solution Approach 1:
The patent combines spectral probing functionality with the existing surface scanning system by integrating additional laser sources and spectrometers into the scanner. This merging approach allows the system to perform both geometric surface registration and qualitative material analysis using a single integrated platform, thereby improving measurement precision without requiring entirely separate systems.
Solution Approach 2:
The enhanced scanner system achieves multi-functionality by incorporating spectral probing capabilities alongside traditional scanning functions. The system can now simultaneously perform surface topography mapping and material composition analysis, making it a universal tool that replaces multiple separate devices and provides comprehensive surface characterization.
2Difficulty of detecting and measuring
If multiple laser sources and spectrometers are integrated, then detection capability is improved, but device complexity increases
Solution Approach 1:
The patent segments the detection system into specialized components: traditional geometric sensors for surface topology and spectral sensors (lasers and spectrometers) for material composition. This segmentation allows each component to be optimized for its specific function while working together within the integrated scanner, improving overall detection capability without creating an unmanageably complex monolithic system.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables comprehensive qualitative analysis and detection of surface features like rust, water, and chemical compositions, providing a higher functionality with enhanced scanning capabilities and warning functions for structural changes.
Implementation Method 1
the surface is spectrally probed in parallel with scanning, i.e. is scanned so that conclusions can be drawn about the composition or the state of the probed or registered surface from the spectral components of the radiation received
Implementation Method 2
spectral probing can be effected for the entire surface topography, in particular continuously, or for partial areas
Data Source
AI summary
The invention relates to a method for registering surfaces, using a scanner system comprising a radiation source for emitting electromagnetic radiation (ES), a scanning device for guiding the radiation over the surface in order to scan the latter and a receiver for receiving the radiation (RS) that is reflected by the surface. According to the invention, the radiation is spectrally separated to analyze the surface characteristics and a distance measuring unit is used to derive distance information in parallel from the received radiation.
