Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Imaging spectrometers with a one-dimensional measuring field of view struggle to stably measure spectral characteristics of objects that move or change position, as they require frequent adjustments to maintain the object within the measuring field, making it difficult to associate the object's position accurately with the measuring field.
Innovation Solution
A spectral characteristics measuring apparatus that combines an imaging spectral device with a two-dimensional imaging device, allowing for accurate association of the object's position with the measuring field of view, even when the positional relation changes, by using a calculation device to determine the range of measurement and correct the correspondence between the measuring fields.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a one-dimensional imaging spectroscope is used to measure spectral characteristics, then spectral measurement precision is improved, but the ability to track moving objects deteriorates because the object falls outside the measuring field of view
Solution Approach 1:
The patent transitions from a one-dimensional line sensor to a two-dimensional area sensor, adding a spatial dimension to the measurement system. This allows the sensor to capture spectral information across a two-dimensional field of view, enabling continuous tracking of moving objects without losing them from the measurement range.
Solution Approach 2:
The area sensor performs multiple functions simultaneously: it captures spectral characteristics while also providing spatial positioning information. The system can measure both the spectral properties and the two-dimensional position of objects within the field of view, making the system adaptable to both stationary and moving targets.
2Device complexity
If the measuring field of view is fixed, then device complexity is reduced, but the ability to associate object position with measuring field deteriorates when positional relations change
Solution Approach 1:
The system uses the two-dimensional position information obtained from the area sensor as feedback to dynamically adjust the spectral measurement process. By continuously monitoring object position and using this information to maintain accurate association between position and spectral data, the system compensates for positional changes without requiring complex mechanical adjustments.
Solution Approach 2:
The patent establishes a predetermined correspondence relationship between the two-dimensional position space and spectral measurement space before actual measurement begins. This pre-established mapping allows the system to quickly and accurately associate object positions with spectral measurements during operation, eliminating the need for real-time complex calculations or adjustments.
