PSF calibration patterns selection based on sensitivity analysis
PSF Calibration was performed with less than 100 calibration measurements. Global sensitivity analysis was successfully employed to determine most representative patterns. Model calibration performed over proposed pattern, sensitive for all parameters of a 3 Gaussian PSF. Tests performed demonstrated efficacy of the method even in presence of noise.
