Fig. 7: Off-centre focus and self-repair capabilities.
From: Continuous design and reprogramming of Totimorphic structures for space applications
A The target focal point can be set off-centre, which is shown here by guiding the focal point of the telescope on a circle around the original focal point. B Selected angle parameters of the lattice as well as the cost during the circular guidance experiment depicted in (A). During optimisation, several discrete target focal points at different angles on the circle were used. C Damage on one of the mirror elements (here: top) adds a deflection to light reflected by this element, thus putting it out of focus. Through reconfiguration of the lattice, the added deflection can be compensated for. D Result for self-repairing a single defect, repeated several times (blue dots). In each repetition, the damaged unit cell and the strength of the damage were selected randomly.
