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.
