ScalarOpticalPathDifference
- class poppy.ScalarOpticalPathDifference(name=None, opd=<Quantity 1. micron>, **kwargs)[source]
Bases:
AnalyticOpticalElementUniform and constant optical path difference
Methods Summary
get_opd(wave)Return the optical path difference, given a wavelength.
Methods Documentation
- get_opd(wave)[source]
Return the optical path difference, given a wavelength.
- In this base class instance, the wavefront parameter ‘wave’ is not used,
and the .opd attribute of the optic is returned directly. Subclasses may change this behavior, for instance to evaluate optical aberrations on the sampling defined for that wavefront, or to compute the wavelength-dependent aberrations of a refractive optic.
- Parameters:
- wavefloat or obj
either a scalar wavelength or a Wavefront object
- Returns:
- ndarray giving OPD in meters
