    • Optical center calibration for aero-engine exhaust temperature field measurement using background-oriented schlieren

    • “Experts propose an optical center correction method based on geometric optics modeling to address the issues of projection offset and axisymmetric temperature field reconstruction distortion caused by camera optical axis deflection in background schlieren technology. This method significantly improves the measurement reliability under non ideal installation and adjustment conditions, providing an effective correction method for high-precision optical diagnosis of tail spray temperature fields in aircraft engines.”
