Rotating Optical Analyzer for Non-Planar Surface Spectral Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional spectral analysis instruments require close contact with the object-to-be-measured for accurate measurements, leading to incorrect results when dealing with non-planar or non-stationary surfaces, as they rely on parallel surface alignment for correct measurement outcomes.
Innovation Solution
An optical analyzer with a rotating part and solid-state light source emitter, allowing for measurements at a distance of at least 5 cm using a light-emitting diode or laser diode, and a light detection device with discontinuous illumination frequencies to improve signal-to-noise ratio and accommodate non-planar or non-stationary surfaces.

Engineering Contradiction Analysis
1Measurement precision
If traditional spectral analysis instruments require close contact with the object-to-be-measured, then sufficient light irradiation and reflected light for measurement can be obtained, but incorrect measured values occur when measuring non-planar or non-stationary surfaces
Solution Approach 1:
The patent transitions from a traditional fixed, contact-based measurement approach to a three-dimensional spatial measurement system. The rotating part enables the light detection device to scan the object surface from multiple angular positions and distances, creating a dimensional shift that allows measurement of non-planar surfaces without direct contact while maintaining measurement accuracy through multi-angle data collection.
Solution Approach 2:
The patent introduces dynamic elements including the rotating part that enables movement of the light detection device, and the discontinuous illumination pattern where light-emitting elements are turned on and off at different frequencies. This dynamic approach allows the system to adapt to non-stationary objects and non-planar surfaces by capturing spectral information from multiple positions and time points, resolving the contradiction between maintaining measurement precision and adapting to varied surface geometries.
2Measurement precision
If the object-to-be-measured surface is kept parallel with the light-emitting elements surface, then correct measurement results are ensured, but the instrument cannot measure non-planar or non-stationary objects
Solution Approach 1:
The rotating part enables the light detection device to dynamically adjust its position and angle relative to the object surface, eliminating the need for manual alignment of parallel surfaces. The system automatically adapts to non-planar and non-stationary objects by scanning from multiple angles, greatly improving ease of operation while maintaining measurement accuracy through computational processing of multi-angle data.
Solution Approach 2:
The patent adds rotational and spatial dimensions to the measurement process, allowing the light detection device to access the object surface from multiple perspectives rather than requiring strict parallel alignment. This dimensional expansion enables measurement of complex geometries without compromising accuracy, as the system processes spectral information collected from various spatial positions.
3Measurement precision
If multiple repeated measurements are performed on non-planar surfaces, then accurate spectral information can be obtained, but measurement time and complexity increase
Solution Approach 1:
The patent employs periodic action through the rotating part that systematically scans the object surface at regular intervals, and through discontinuous illumination where light-emitting elements are activated at specific frequencies. This periodic scanning approach efficiently collects spectral information from multiple positions in a structured manner, obtaining accurate spectral data for non-planar surfaces while minimizing measurement time through automated sequential sampling rather than manual repeated measurements.
