A birefringent device, which is configured to be mounted in an optical path of an optical system, has an effective area in a pupil plane. The birefringent device affects different polarization states differently and position-dependently. The birefringent device realizes a first pupil function assigned to a first polarization state and a second different pupil function assigned to a second polarization state. The pupil functions may be optimized to achieve various specific optical properties like extended depth of field.

A method of processing signal data comprises receiving signal data, calculating a first k-th moment from the signal data based on a first number of samples N, calculating a second k-th moment from the signal data based on a second number of samples N, the first number Nbeing different than the second number N, calculating a combined error, the combined error being a function of the first and second k-th moments, classifying a data region of the signal data as flat if the combined error is below or equal to a threshold curve in the data region, and classifying a data region of the signal data as non-flat if the combined error is higher than the threshold curve in the data region.
