The SOPHI (Segmented Optics PHase Integration) Phase 1 project has demonstrated the original goals for the SOPHI breadboard to enable it to meet the challenge of the Phase II full 1 meter optical quality segmented mirror project: one of these goals is that the mirror segments can be phased without edge sensors and without referencing each other (no 2 π ambiguities). To do this, an optical metrology is utilized (the subject of a separate paper and reference 1). The stiffness and lightweight criteria are met by utilizing CSIC and Cesic ceramics.
