Engineering Contradiction Analysis
1Ease of operation
If separate control signals are used for one-dimensional and two-dimensional image acquisition, then the system can independently control different acquisition processes, but the timing non-correspondence causes image errors and misalignment in three-dimensional image formation
Solution Approach 1:
The patent combines the one-dimensional image acquisition control signal and two-dimensional image acquisition control signal into a single integrated control signal. This integration ensures that the timing information for both 1D and 2D acquisitions is synchronized, eliminating the misalignment and image errors that occur when separate control signals are used. The merged control signal maintains independent control capabilities while ensuring temporal correspondence between different acquisition processes.
2Productivity
If one-dimensional images are captured at different time intervals to form two-dimensional images, then the system can acquire spatial information, but the lack of timing synchronization between 1D and 2D control signals results in image errors
Solution Approach 1:
The patent incorporates timing information directly into the control signal generation process, establishing the temporal relationship between one-dimensional and two-dimensional acquisitions before the actual image capture begins. By pre-synchronizing the timing information in the control signals, the system ensures that 1D images captured at different time intervals are properly aligned when forming 2D images, preventing image errors while maintaining high acquisition speed.

AI summary
A signal control module integrated to a low coherence interferometry including a one-dimensional (1D) array image sensor is provided. The signal control module includes an image acquisition controller and a signal controller. The image acquisition controller sends a 1D image acquisition control signal. The signal controller sends a two-dimensional (2D) image acquisition control signal, wherein the 1D and 2D image acquisition control signals are synchronized with each other. The 1D array image sensor captures 1D image information of an object-to-be-tested at different positions along a direction according to the 1D and 2D image acquisition control signals. The 1D image information constitutes 2D image information. Furthermore, a low coherence interferometry is provided.
