Engineering Contradiction Analysis
1Measurement precision
If the correspondence relationship between emission directions and detection elements is estimated using conventional methods, then the system can operate with simple configuration, but the detection accuracy and alignment precision deteriorate due to misalignment between estimated and actual relationships
Solution Approach 1:
The system performs preliminary calibration by actually irradiating electromagnetic waves in various emission directions and detecting the reflected waves to obtain the actual correspondence relationship between emission directions and detection elements. This preliminary action establishes accurate alignment information before actual measurement operations, eliminating the need for complex real-time alignment calculations and improving detection accuracy without significantly increasing operational complexity.
Solution Approach 2:
The system uses the detected correspondence relationship as feedback to correct and update the alignment information between the irradiator and detector. By continuously comparing estimated versus actual correspondence relationships and applying corrections, the system maintains high detection accuracy while using a relatively simple configuration. The feedback mechanism allows the system to adapt and improve performance based on actual measurement data.
2Productivity
If multiple detection elements are used to detect reflected waves from different irradiation positions, then the system can acquire information from multiple regions simultaneously, but the coordinate system alignment and data integration become more complex
Solution Approach 1:
The correspondence relationship information acts as an intermediary that connects the coordinate systems of multiple detection elements to the irradiator's emission directions. By establishing this intermediate reference framework through actual calibration measurements, the system can integrate data from multiple detection elements without requiring complex real-time coordinate transformations. The intermediary relationship simplifies data fusion while enabling simultaneous multi-region information acquisition.

AI summary
An electromagnetic wave detection apparatus (10) includes an irradiator (11), a first detector (17), a memory (13), and a controller (14). The irradiator (11) irradiates electromagnetic waves. The first detector (17) includes detection elements. The detection elements detect, by irradiation position, reflected waves of the electromagnetic waves irradiated onto an object (ob). The memory (13) stores related information. The related information is information associating any two of the emission direction of the electromagnetic waves and elements defining two points on a path. The path refers to a path of the electromagnetic waves emitted from the irradiator (11) to the first detector (17) via the object (ob). The controller (14) updates the related information based on the emission direction of the electromagnetic waves and the position of the detection element, among the detection elements, that detects the reflected waves of the electromagnetic waves.
