Solution Overview
Problem
Existing electromagnetic wave detection systems face challenges in aligning the detection axes of multiple detectors, leading to differences in coordinate systems and making it difficult to achieve uniform imaging and accurate information acquisition.
Innovation Solution
The proposed electromagnetic wave detection apparatus includes a configuration with an irradiator, a reflector, a separation unit, and multiple detectors, where the separation unit separates electromagnetic waves into different directions, and a switch adjusts the propagation paths to align the detection axes of the detectors, thereby reducing coordinate system misalignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple detectors are used to acquire surrounding information, then the quantity of information acquired is improved, but the misalignment between detection axes causes coordinate system differences and reduces measurement precision
Solution Approach 1:
A light guide is introduced as an intermediary component to physically align the detection axes of multiple detectors. The light guide directs electromagnetic waves from a common direction to each detector, ensuring that all detectors observe the object from the same optical path and coordinate system, thereby eliminating misalignment issues while maintaining multi-detector information acquisition
2Measurement precision
If the detection axes of multiple detectors are aligned, then the coordinate system consistency is improved, but the device complexity increases due to additional alignment mechanisms
Solution Approach 1:
The light guide serves as a simple intermediary optical component that passively aligns detection axes without requiring complex active control mechanisms. By using a static light guide structure rather than dynamic adjustment mechanisms, the patent achieves coordinate system consistency while minimizing added device complexity
Solution Approach 2:
The light guide combines multiple detection paths into a single optical origin point. By merging the optical paths of multiple detectors through a common light guide entrance, the system achieves axis alignment without requiring separate adjustment mechanisms for each detector, thereby reducing overall system complexity

Implementation Method 1
a separation unit configured to separate electromagnetic waves incident on the separation unit so that the electromagnetic waves propagate in a first direction and a second direction
Implementation Method 2
The electromagnetic waves that propagate in the second direction are caused to propagate in a third direction in the first state and the electromagnetic waves that propagate in the second direction are caused to propagate in a fourth direction in the second state
Implementation Method 3

AI summary
An electromagnetic (EM) wave detection apparatus includes an irradiator that emits EM waves and a reflector that changes an irradiation position of the EM waves on an object by changing a direction of the emitted EM waves. A separation unit separates EM waves incident thereon to propagate the EM waves in first and second directions. A first detector detects the EM waves in the first direction. A switch includes plural switching elements that can switch between first and second states. EM waves in the second direction are caused to propagate in a third direction in the first state and caused to propagate in a fourth direction in the second state. A second detector detects the EM waves in the third direction. The switch switches each of the plurality of switching elements between the first and second states according to the direction in which the reflector reflects the EM waves.
