Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of magnification settings is required when switching between observation modes, then the system can provide precise control over imaging parameters, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The system pre-sets the projection magnification of the intermediate image to appropriate values for each observation mode (superresolution mode requires at least twice the aperture size, normal mode uses lower magnification). When the user selects an observation mode, the control apparatus automatically configures the magnification setting in advance, eliminating the need for manual adjustment during operation.
Solution Approach 2:
The control apparatus automatically adjusts the projection magnification based on the selected observation mode without requiring user intervention. The system serves itself by internally managing the magnification parameter changes, thereby simplifying the user interface while maintaining precise control over imaging parameters.
2Adaptability or versatility
If manual adjustment of magnification settings is required when switching between observation modes, then the system allows flexible control over imaging parameters, but errors and time loss occur due to manual adjustment requirements
Solution Approach 1:
The system pre-configures the appropriate projection magnification for each observation mode. For superresolution observation, the magnification is set to ensure the intermediate image is at least twice the aperture size; for normal observation, a lower magnification is pre-set. This preliminary configuration ensures that when mode switching occurs, the correct parameters are already in place, preventing user errors.
Solution Approach 2:
The control apparatus receives input from the user regarding the selected observation mode and automatically adjusts the projection magnification accordingly. This feedback mechanism ensures that the system responds appropriately to mode changes, maintaining the correct relationship between intermediate image size and aperture dimensions, thereby ensuring reliable and accurate observations.
3Measurement precision
If the projection magnification of the intermediate image is increased to achieve superresolution, then the aperture coverage improves, but the system complexity increases due to the need for intermediate scaling optical system
Solution Approach 1:
The intermediate scaling optical system serves multiple functions: it adjusts the projection magnification of the intermediate image to ensure proper aperture coverage for superresolution observation, and it can be integrated into the existing imaging optical system without requiring separate dedicated components. This multi-functionality reduces overall system complexity while achieving the desired superresolution capability.

AI summary
A system includes an imaging optical system that forms an optical image of an observed object; a control apparatus that switches between a superresolution observation mode and a normal observation mode; and a rotatable disk located at a position conjugate to a front focal position of the imaging optical system and having a plurality of apertures. The imaging optical system changes a projection magnification of an intermediate image that is a point image of a portion of the observed object that is formed on the disk. The control apparatus sets, during the superresolution observation mode, the projection magnification in a manner such that the intermediate image becomes at least twice as large as the apertures and sets, during the normal observation mode, the projection magnification in a manner such that the projection magnification becomes lower than the projection magnification in the superresolution observation mode.
