Figure 1From: Inverse ray mapping in phase space for two-dimensional reflective optical systemsShape of the two-faceted cup. Each line of the system is labeled with a number. The source \(\mathsf{S}= [-2,2]\) (line 1) is located on the x-axis. The target \(\mathsf{T}= [-17, 17]\) (line 4) is parallel to the source and is located at a height \(z= 40\). The left and right reflectors (lines 2 and 3) connect the source with the targetBack to article page
