Figure 6-8. SAO refractive design.<br />
Beyond the optimization of the conception design and laboratory demonstrations, there is much<br />
research that must be done in order to understand the issues related to system integration,<br />
operation and requirements flow down. For example, while conventional pupil-apodized or<br />
shaped-pupil coronagraphs enjoy a relatively low level of aberration sensitivity, it is not known<br />
whether a phase-induced apodization would offer the same benefits. Areas of needed study are<br />
issues related to PIAA optical alignment sensitivity and the PIAA interaction with the wavefront<br />
control system architecture that affect continuous, searchable, discovery spaces.<br />
