SFRplus MTF Automatic Calculation Software

Powered by our in-house developed algorithm core, this SFRplus‑based MTF automatic calculation software is a high-performance alternative comparable to Imatest for camera and lens image quality evaluation. It supports fully automatic slanted-edge detection and MTF computation, enabling simultaneous multi-region analysis across the full field‑of‑view, covering center, edge and corner positions.

Features:

• Fully automated slanted-edge detection & MTF calculation

• Multi-region simultaneous analysis (center, edge, corner) across the entire field of view

• Integrated measurement: MTF/SFR, distortion, lateral chromatic aberration (LCA), color accuracy, gamma, noise

• Batch processing & auto-reporting (PDF/Excel/CSV) with Pass/Fail criteria

• Pre-distortion chart support for wide-angle/fisheye lenses

• Standardized outputs: MTF50/MTF30/NQMTF, lp/mm, cycle/pixel, FOV, geometric distortion

  
  

Advantages:

• Zero manual ROI selection: Eliminates human error and reduces analysis time from minutes to seconds

• Full-field characterization: Captures sharpness non-uniformity vs. limited point sampling

• All-in-one testing: Replaces multiple test charts/tools with one SFRplus solution

• High repeatability & traceability: Consistent results for R&D and production QC

• Wide lens compatibility: Accurate analysis for low- and high-distortion optical systems

  
  

Benefits:

• Faster R&D cycles: Accelerate lens/camera optimization with reliable, repeatable MTF data

• Lower testing costs: Reduce hardware, labor, and workflow complexity

• Improved product quality: Ensure sharpness, uniformity, and color performance meet specs across the entire image

• Scalable production QC: Automate inline testing with objective Pass/Fail decisions

• Compliance & documentation: Generate audit-ready reports for ISO, IEC, and customer standards
