finesse.tracing.tree.TraceTree

Overview

class finesse.tracing.tree.TraceTree(node, dependency)

Bases: object

A binary tree data structure representing all the beam tracing paths from some root optical node of a model.

Each instance of this class has a left and right sub-tree (of the class type) and a parent tree. These linked tree attributes can be None. If the tree has a left / right sub-tree then the memoryviews left_abcd_x, left_abcd_y etc. will be initialised from the numerical ABCD matrix from the tree’s optical node to the next tree’s optical node.

Every sub-tree has a dependency attribute which is the object that the trace tree depends on - either a Cavity or a Gauss instance.
