Calculate the Optical Path Difference (OPD) map at the retina surface.
- Parameters:
- backendOptilandBackend
Reference to the Optiland backend.
- field_coordinateFieldCoordinate | None
The coordinate of the field for which the wavefront is calculated. If None, the current field coordinate will be used.
- wavelengthfloat | None
The wavelength for which the wavefront is calculated, in μm. If None, the current wavelength will be used.
- field_typeFieldType
The type of field coordinate provided. Either ‘angle’ (degrees) or ‘object_height’ (mm). Defaults to ‘angle’.
- samplingSampleSize | str | int
The sampling of the OPD map. Can be an integer (e.g., 128 for 128x128), a string like ‘128x128’, or a SampleSize object. Defaults to 128.
- remove_tiltbool, optional
If True, the tilt component is removed from the OPD map. Defaults to True.
- use_exit_pupil_shapebool, optional
If True, the OPD map is distorted to show the shape of the exit pupil. Defaults to False. Optiland does not support this feature. A warning will be issued if set to True, and the parameter will be ignored.
- Returns:
- DataFrame
A pandas DataFrame containing the OPD map values in waves.
- OPD
The raw analysis result from the backend.
