Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual alignment adjustment is used between fiber end and light detector, then alignment can be achieved, but it requires substantial labor and time
Solution Approach 1:
The system performs self-alignment by automatically detecting the light receiver's position relative to the fiber end and adjusting the fiber end position accordingly, eliminating the need for manual alignment operations
Solution Approach 2:
The light receiver detects the position of the fiber end and provides feedback signals to the position adjusting mechanism, creating a closed-loop control system that automatically maintains optimal alignment
2Measurement precision
If manual alignment adjustment is used between fiber end and light detector, then alignment can be achieved, but it requires calling servicemen from maintenance service companies
Solution Approach 1:
The system performs self-alignment by automatically detecting the light receiver's position relative to the fiber end and adjusting the fiber end position accordingly, eliminating the need for manual alignment operations
Solution Approach 2:
The patent replaces manual mechanical alignment operations with an automated system combining optical detection (light receiver) and mechanical positioning (position adjusting mechanism), substituting human labor with automated devices
3Measurement precision
If fixed positional relationship between fiber end and light detector is maintained, then alignment can be achieved initially, but it is easily altered by shock or environmental conditions
Solution Approach 1:
The system transitions from a static fixed alignment to a dynamic adjustable alignment, where the fiber end position can be automatically adjusted in response to environmental changes or shocks to maintain optimal alignment
Solution Approach 2:
The light receiver continuously monitors the alignment between fiber end and detector, providing feedback to the position adjusting mechanism to compensate for disturbances and maintain stable alignment
4Measurement precision
If precise alignment between fiber end and light-receiving surface is required, then image quality can be ensured, but the alignment is difficult to maintain due to the minute fiber end surface
Solution Approach 1:
The system performs self-alignment by automatically detecting the light receiver's position relative to the fiber end and adjusting the fiber end position accordingly, eliminating the need for manual alignment operations
Solution Approach 2:
The patent replaces manual mechanical alignment operations with an automated system combining optical detection (light receiver) and mechanical positioning (position adjusting mechanism), substituting human labor with automated devices

AI summary
An optical image measuring device, like a Spectral-Domain Optical Coherence Tomograph, forms an image of an object to be measured based on a result of light-receiving by a light-receiving part like a CDD camera (184) as part of a spectrometer. This optical image measuring device comprises: a specifying part configured to specify the light irradiated state of the light-receiving surface of the light-receiving part with respect to a light guiding part (165), like an optical fibre, and a dispersion part (182); and an altering part (244) configured to alter the relative position and/or orientation between a light-receiving surface and the exit end (165a) of the light guiding part (165), based on the light irradiated state.The light irradiated state is an indication of how the light impinges on the surface of the detector (184).
