InverseTransmission
(optic=None)[source]¶ Bases:
poppy.optics.AnalyticOpticalElement
Given any arbitrary OpticalElement with transmission T(x,y) return the inverse transmission 1 - T(x,y)
This is a useful ingredient in the SemiAnalyticCoronagraph algorithm.
Attributes Summary
shape
Return shape of the OpticalElement, as a tuple Methods Summary
display
(**kwargs)Display plots showing an optic’s transmission and OPD. get_opd
(wave)Return the optical path difference, given a wavelength. get_transmission
(wave)Note that this is the amplitude transmission, not the total intensity transmission. Attributes Documentation

display
(**kwargs)[source]¶ Display plots showing an optic’s transmission and OPD.
- what : str
- What to display: ‘intensity’, ‘amplitude’, ‘phase’, ‘opd’, or ‘both’ (meaning intensity and OPD in two subplots)
- ax : matplotlib.Axes instance
- Axes to display into
- nrows, row : integers
- number of rows and row index for subplot display
- crosshairs : bool
- Display crosshairs indicating the center?
- colorbar : bool
- Show colorbar?
- colorbar_orientation : bool
- Desired orientation, horizontal or vertical? Default is horizontal if only 1 row of plots, else vertical
- opd_vmax : float
- Max absolute value for OPD image display, in meters.
- title : string
- Plot label
- wavelength : float, default 1 micron
- For optics with wavelength-dependent behavior, evaluate at this wavelength for display.
- npix : integer
- For optics without a fixed pixel sampling, evaluate onto this many pixels for display.
- grid_size : float
- For optics without a fixed pixel sampling, evaluate onto this large a spatial or angular extent for display. Specify in units of arcsec for image plane optics, meters for all other optics. If unspecified, a default value will be chosen instead, possibly from the ._default_display_size attribute, if present.
