CircularAperture

class poppy.CircularAperture(name=None, radius=<Quantity 1. m>, pad_factor=1.0, planetype=PlaneType.unspecified, gray_pixel=True, **kwargs)

Bases: AnalyticOpticalElement

Defines an ideal circular pupil aperture

Parameters:

namestring

Descriptive name

radiusfloat

Radius of the pupil, in meters. Default is 1.0

gray_pixelbool

Apply gray pixel approximation to return fractional transmission for edge pixels that are only partially within this aperture?

pad_factorfloat, optional

Amount to oversize the wavefront array relative to this pupil. This is in practice not very useful, but it provides a straightforward way of verifying during code testing that the amount of padding (or size of the circle) does not make any numerical difference in the final result.

Methods Summary

get_transmission(wave)

Compute the transmission inside/outside of the aperture.
