DESCRIPTION:The ultrafast evolution of the physical process in the laser dr
 iven inertial confinement (ICF) fusion requires ultrafast imaging diagnost
 ic instruments. The traditional commercial instruments are not able to mee
 t the ICF experiment requirement. It is a technical challenge to develop t
 he diagnostic instruments with an extreme capbility. This work proposes a 
 three-layer MBSE logical design framework for an ultrafast framing imager.
  The framework comprises an operational analysis layer\, a system design l
 ayer\, and a component design layer. Using SysML as the unified modeling l
 anguage\, it progressively decomposes the experimental objective of acquir
 ing picosecond-scale plasma-evolution images into system indicators\, func
 tional nodes\, logical components\, and module-level parameters. Methodolo
 gically\, the study establishes a bidirectional requirements-traceability 
 mechanism and introduces a parameter-budget model for temporal-resolution 
 allocation. Taking system temporal resolution <= 80 ps as the representati
 ve case\, a complete decomposition chain is constructed from the user requ
 irement down to triggersynchronization jitter\, gating-pulse jitter\, and 
 MCP response time. Process-based comparative analysis further confirms the
  effectiveness of the framework in requirement allocation\, change-impact 
 localization\, and cross-disciplinary collaboration. The case study shows 
 that\, at the same problem scale\, the MBSE approach reduces the time requ
 ired for requirement-to-module allocation from approximately 6.4 h to 2.1 
 h\, and shortens the impact-localization time for tightening the target fr
 om 0 ps to 50 ps from 47 min to 11 min\, while significantly reducing omis
 sions. Model statistics indicate that the case includes 5 user requirement
 s\, 8 system indicators\, 17 functional nodes\, 12 key interfaces\, and 46
  traceability links\, demonstrating not only conceptual value but also mai
 ntainability at a practical engineering scale. The proposed method therefo
 re provides a useful foundation for the systematic design\, rapid iteratio
 n\, and subsequent automated verification of laser-fusion diagnostic equip
 ment.
