- property Cavity.is_changing¶
Flag indicating whether any geometric parameter inside the cavity is changing.
A geometric parameter is defined as one of:
radii of curvature of surfaces,
focal lengths of lenses,
angles of incidence of beam splitters,
lengths of spaces,
refractive indices of spaces,
i.e. any parameter which can affect the ABCD matrix values.
