WedgeSegmentedCircularAperture¶
- class poppy.WedgeSegmentedCircularAperture(name=None, radius=<Quantity 1. m>, rings=2, nsections=4, gap_radii=None, gap=<Quantity 0.01 m>, gray_pixel=False, rotation=0, **kwargs)[source]¶
Bases:
MultiSegmentAperture,CircularApertureDefine a circular aperture made of pie-wedge or keystone shaped segments.
- Parameters:
- namestring
Descriptive name
- radiusfloat
Radius of the pupil, in meters.
- ringsint
Number of rings of segments
- nsectionsint or list of ints
Number of segments per ring. If one int, same number of segments in each ring. Or provide a list of ints to set different numbers per ring. To exclude the center for an on-axis aperture, provide a 0 as the first element of nsections to indicate 0 segments in the first ring.
- gap_radiiquantity length
Radii from the center for the gaps between rings
- gapquantity length
Width of gaps between segments, in both radial and azimuthal directions
- gray_pixelbool, optional
Apply gray pixel approximation to return fractional transmission for edge pixels that are only partially within this aperture? (Note, currently this gives a warning; disabled by default)
- kwargsother kwargs are passed to CircularAperture
- Potential TODO: also have this inherit from MultiSegmentedAperture and subclass
- some of those functions as appropriate. Consider refactoring from gap_radii to instead
- provide the widths of each segment. Add option for including the center segment or having
- a missing one in the middle for on-axis apertures. Use grayscale approximation for rasterizing
- the circular gaps between the rings.
Methods Summary
get_transmission(wave)Compute the transmission inside/outside of the aperture.
