Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mirror systems are used to capture and reconstruct three-dimensional images, then true three-dimensional reconstruction is possible, but the device complexity and space requirements increase significantly
Solution Approach 1:
The patent extracts and eliminates the mirror components from the optical system. Instead of using convex mirrors to capture and reconstruct three-dimensional images, the invention uses a pinhole camera approach with a curved negative support surface that directly records the three-dimensional light field information, removing the complex mirror arrangement while maintaining reconstruction capability
Solution Approach 2:
The patent replaces the mechanical mirror-based optical system with a pinhole camera system that uses a curved negative support surface. This substitution eliminates the need for precise mechanical alignment of mirrors and reduces the overall system complexity while achieving the same three-dimensional reconstruction function
2Reliability
If two convex mirrors are used for three-dimensional reproduction, then true three-dimensional image reconstruction is achieved, but the space requirements and component costs increase
Solution Approach 1:
The patent merges the functions of the two convex mirrors into a single pinhole camera system with a curved negative support surface. This consolidation integrates the light field capture and reconstruction functions into one compact unit, significantly reducing the space requirements while maintaining the three-dimensional reconstruction capability
Solution Approach 2:
The patent implements a nested structure where the curved negative support surface is positioned within the pinhole camera housing. This nesting allows the three-dimensional reconstruction function to be embedded within a compact form factor, reducing the overall system footprint compared to the external mirror arrangement
3Loss of information
If multiple images are captured at different angles to record angular distribution, then complete three-dimensional information is obtained, but the number of image elements and processing effort increase proportionally
Solution Approach 1:
The patent transitions from capturing multiple two-dimensional images at different angles to capturing a single three-dimensional light field distribution using a curved negative support surface. This dimensional transformation allows all angular information to be recorded simultaneously in one exposure, eliminating the need for multiple images and reducing processing effort

Function Achieved in This Case
The solution enables the generation and transmission of more realistic three-dimensional images and films, reducing complexity and space requirements while allowing for flexible component arrangement and cost-effective implementation using planar detectors.
Implementation Method 1
The aperture opening is designed such that the spatial distribution of the passing light in the region of the aperture differs due to the propagation angle
Implementation Method 2
the detector is an angle-resolving detector configured to detect the intensity of the light emitted by the three-dimensional object across the angle around the aperture
Implementation Method 3
The emitter is an angle-resolving emitter configured to emit light, corresponding to a known intensity distribution of the light emitted by a three-dimensional object, across an angle to the aperture

AI summary
The present invention relates to devices (1; 101) for recording, transmitting, and reconstructing images of a three-dimensional object (5), as well as a method for recording, transmitting, and reconstructing images of a three-dimensional object (5), and furthermore to a system comprising the recording device (1) and the transmission device (101), and comprising: an aperture (3, 103), a detector (4), a transmission medium (700), and an emitter (120). First, the angular distribution of the light emitted by a three-dimensional object (5) in front of an aperture (3) is detected behind the aperture (3) by a detector (4) and transmitted to an emitter (120) by means of a suitable transmission medium (700). The emitter then emits light onto a second aperture (103) according to the angular distribution, thereby creating a virtual object (105) behind the second aperture (103).
