Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If Raman spectroscopy is used for spectroscopic analysis, then diagnostic information can be obtained from observation targets, but optical power loss due to damage or connection failures cannot be accurately detected
Solution Approach 1:
The return light is segmented into multiple wavelength bands using a diffraction grating and wavelength separation optics. By separating the return light into different wavelength components, the system can independently analyze signals from different sources (optical member, optical fiber, connector) and accurately detect optical power loss without affecting the diagnostic analysis of the observation target.
2Ease of operation
If optical probes are used for spectroscopic analysis, then signal light can be acquired from observation targets, but problem identification requires specialized knowledge and reduces operational ease
Solution Approach 1:
The system provides automated feedback by analyzing the spectral characteristics of return light and automatically identifying the source and nature of problems. The wavelength separation portion and analysis portion generate diagnostic information that automatically indicates whether issues originate from the optical member, optical fiber, or connector, eliminating the need for operators to have specialized knowledge for problem identification.
3Adaptability or versatility
If detachable connectors are used for optical probe attachment, then device adaptability is improved, but connection failures and optical power loss become more frequent
Solution Approach 1:
The system performs preliminary detection of connection status and optical power loss by analyzing the spectral characteristics of return light before diagnostic measurements are taken. The wavelength separation portion identifies connection issues and optical fiber damage early, allowing operators to address potential problems before they affect the reliability of diagnostic measurements, thus compensating for the inherent instability of detachable connectors.

AI summary
Provided is a spectroscopic analysis apparatus including: an optical probe; and a spectroscopic analysis portion to which the optical probe is attached. The optical probe includes an optical fiber that guides illumination light coming from a light source and signal light coming from an observation target and an optical member that is disposed at least at a distal end of the optical fiber. The spectroscopic analysis portion includes an information separation portion that generates wavelength dependent characteristics by optically dispersing the signal light and that separates, from information about the signal light, information about first return light returning from the optical member and information about second return light returning from the optical fiber, a problem determining portion that determines a problem occurring at the optical probe based on the separated first return light and second return light, and a notification portion that notifies information about the determined problem.
