plot3D()

tuple[pt.Figure, pt.Axes] PyPO.System.System.plot3D	(		self,

Plot a 3D reflector.

Note that matplotlib offers custom control over figures in the matplotlib window. This means that most parameters described for this method can be adjusted in the matplotlib plotting window.

Parameters

cmap	Colormap of reflector. Default is cool.
norm	Plot reflector normals. Default is False.
fine	Spacing of normals for plotting. Default is 2.
show	Show plot. Default is True.
foc1	Plot focus 1. Default is False.
foc2	Plot focus 2. Default is False.
save	Save the plot.
ret	Return Figure and Axis. Only used in GUI.

Returns

fig Figure object.

ax Axes object.

plotBeam2D()

		bool	unwrap_phase = False,
		bool	ret = False
	)

Generate a 2D plot of a PO (scalar)field or current.

Note that matplotlib offers custom control over figures in the matplotlib window. This means that most parameters described for this method can be adjusted in the matplotlib plotting window.

Parameters

name_obj	Name of field or current to plot.
comp	Component of field or current to plot. String of two characters; an uppercase {E, H, J, M} for field followed by a lowercase {x, y, z} for component. (e.g: 'Jz')
contour	A PyPO field or current component to plot as contour.
contour_comp	Component of contour to plot as contour. If None, assumes the contour is a scalarfield.
vmin	Minimum amplitude value to display. Default is -30.
vmax	Maximum amplitude value to display. Default is 0.
levels	Levels for contourplot.
show	Show plot. Default is True.
amp_only	Only plot amplitude pattern. Default is False.
save	Save plot to /images/ folder.
norm	Normalise field (only relevant when plotting linear scale). Default is True.
aperDict	Plot an aperture defined in an aperDict object along with the field or current patterns. Default is None.
scale	Plot amplitude in linear or decibel values. Instance of Scales enum object.
project	Set abscissa and ordinate of plot. Should be given as an instance of the Projection enum. Default is Projection.xy.
units	The units of the axes. Instance of Units enum object.
name	Name of .png file where plot is saved. Only when save=True. Default is "".
titleA	Title of the amplitude plot. Default is "Amp".
titleP	Title of the phase plot. Default is "Phase".
unwrap_phase	Unwrap the phase patter. Prevents annular structure in phase pattern. Default is False.
ret	Return the Figure and Axis object. Default is False.

Returns

fig Figure object.

ax Axes object.

plotBeamCut()

tuple[pt.Figure, pt.Axes] PyPO.System.System.plotBeamCut	(		self,
		str	name_field,
		FieldComponents	comp,
		float	vmin = None,
		float	vmax = None,
		bool	center = True,
		bool	align = True,
		Scales	scale = Scales.dB,
		Units	units = Units.DEG,
		str	name = "",
		bool	show = True,
		bool	save = False,
		bool	ret = False
	)

Plot beam pattern cross sections.

Plot the beam cross sections for a PO field. In this case, calcBeamCuts() will try to translate and rotate the supplied beam pattern to lie along the x- and y-axes. Note that using the "center" and "align" arguments should not be done when plotting beam cuts of very non-Gaussian beams. For these patterns, it is advised to set the arguments to False and calculate the beam cuts as-is.

Parameters

name_field	Name of field object.
comp	Component of field object. Instance of FieldComponents enum object.
comp_cross	Cross-polar component. If given, is plotted as well. Defaults to None.
vmin	Minimum amplitude value to display. Default is -30.
vmax	Maximum amplitude value to display. Default is 0.
center	Whether to calculate beam center and center the beam cuts on this point.
align	Whether to find position angle of beam cuts and align cut axes to this.
scale	Plot in decibels or linear.
units	The units of the axes. Instance of Units enum object.
name	Name of .png file where plot is saved. Only when save=True. Default is "".
show	Show plot. Default is True.
save	Save plot to savePath.
ret	Return the Figure and Axis object. Default is False.

Returns

fig Figure object.

ax Axes object.

plotGroup()

tuple[pt.Figure, pt.Axes] PyPO.System.System.plotGroup	(		self,
		str	name_group,
		bool	show = True,
		bool	ret = False
	)

Plot a group of reflectors.

Note that matplotlib offers custom control over figures in the matplotlib window. This means that most parameters described for this method can be adjusted in the matplotlib plotting window.

Parameters

name_group	Name of group to be plotted.
show	Show the plot.
ret	Whether to return figure and axis.

Returns

fig Figure object.

ax Axes object.

plotRTframe()

def PyPO.System.System.plotRTframe	(		self,
		str	name_frame,
		Projections	project = Projections.xy,
		bool	ret = False,
		float	aspect = 1,
		Units	units = Units.MM
	)

Create a spot diagram of a ray-trace frame.

Note that matplotlib offers custom control over figures in the matplotlib window. This means that most parameters described for this method can be adjusted in the matplotlib plotting window.

Parameters

name_frame	Name of frame to plot.
project	Set abscissa and ordinate of plot. Should be given as an instance of the Projection enum. Default is Projection.xy.
ret	Return Figure and Axis. Default is False.
aspect	Aspect ratio of plot. Default is 1.
units	Units of the axes for the plot. Instance of Units enum object.

Returns

fig Figure object.

ax Axes object.

plotSystem()

tuple[pt.Figure, pt.Axes] PyPO.System.System.plotSystem	(		self,
		cm	cmap = cm.cool,
		bool	norm = False,
		int	fine = 2,
		bool	show = True,
		bool	foc1 = False,
		bool	foc2 = False,
		bool	save = False,
		bool	ret = False,
		list[str]	select = None,
		list[str]	RTframes = None,
		str	RTcolor = "black"
	)

Plot the current system.

Plots the reflectors and optionally ray-trace frames in a 3D plot.

The ray-trace frames to plot are supplied as a list to the "RTframes" parameter. Note that matplotlib offers custom control over figures in the matplotlib window. This means that most parameters described for this method can be adjusted in the matplotlib plotting window.

Parameters

name_surface	Name of reflector to plot.
cmap	Colormap of reflector. Default is cool.
norm	Plot reflector normals. Default is False.
fine	Spacing of normals for plotting. Default is 2.
show	Show plot. Default is True.
foc1	Plot focus 1. Default is False.
foc2	Plot focus 2. Default is False.
save	Save the plot.
ret	Return Figure and Axis. Only used in GUI.
select	A list of names of reflectors to plot. If not given, plot all reflectors.
RTframes	A list of names of frame to plot. If not given, plot no ray-trace frames.

Returns

fig Figure object.
