Solution Overview
Problem
Existing electromagnetic wave detection apparatuses face challenges in downsizing while maintaining the homogenization of electromagnetic wave intensity for secondary images, and in avoiding interference between primary and secondary image forming systems.
Innovation Solution
The apparatus employs a progression unit that directs electromagnetic waves to a secondary image forming optical system without leakage, using a configuration where the primary image forming optical system does not include an aperture near its front focal point, and the secondary image forming optical system is designed to minimize vignetting and intensity unevenness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional electromagnetic wave detection apparatus includes an aperture near the front focal point of the primary image forming optical system, then the apparatus can collect sufficient electromagnetic waves, but the apparatus size increases and interference between primary and secondary image forming systems occurs
Solution Approach 1:
The patent removes the aperture from the primary image forming optical system, extracting the component that causes both size increase and interference. By eliminating this element, the apparatus achieves downsizing while avoiding interference between the primary and secondary image forming systems, as the electromagnetic waves can progress to the secondary system without being blocked or scattered by the aperture.
Solution Approach 2:
The patent introduces a progression unit that changes the progression direction of electromagnetic waves, adding a dimensional transformation function. This allows the system to redirect electromagnetic waves from the primary image forming path to the secondary image forming path without requiring physical separation through apertures, thereby reducing apparatus size while maintaining detection efficiency.
2Illumination intensity
If the secondary image forming optical system uses a conventional configuration, then the system can form secondary images, but electromagnetic wave intensity becomes uneven and vignetting occurs
Solution Approach 1:
The patent applies local quality by making the progression unit's reflection surface tiltable at different angles for different regions. By adjusting the tilt angle according to the incident angle of electromagnetic waves from different directions, each local region of the progression unit optimizes the progression direction, ensuring uniform electromagnetic wave intensity distribution across the secondary image while avoiding vignetting.
3Illumination intensity
If the progression unit redirects electromagnetic waves at large angles, then the secondary image can be formed with good intensity homogeneity, but electromagnetic wave leakage increases
Solution Approach 1:
The patent implements dynamics by making the progression unit tiltable, allowing real-time adjustment of the progression direction based on the incident electromagnetic waves. This dynamic adjustment enables the system to optimize the redirection angle for each region, achieving good intensity homogeneity in the secondary image while minimizing electromagnetic wave leakage by precisely controlling the progression directions.

AI summary
An electromagnetic wave detection apparatus includes a first image forming unit, a progression unit, a second image forming unit, and a first detector. The first image forming unit forms an image of incident electromagnetic waves. The progression unit includes a plurality of pixels arranged along a reference surface. The progression unit causes electromagnetic waves incident on the reference surface from the first image forming unit to progress in a first direction. The second image forming unit forms an image of electromagnetic waves progressing in the first direction. The first detector detects incident electromagnetic waves from the second image forming unit. An angle formed by a progression axis at each angle of view of electromagnetic waves that have passed the first image forming unit and a principal axis of the first image forming unit is equal to or smaller than a predetermined value.
