Descriptive title |
Short description and specific objectives of the
task |
| 04200 |
Metrology |
Objectives: feasibility and performance of a
metrology system for coarse alignment of the optics. Ditto
for low cost position sensors for the phasing of segments.
Tasks: development/testing of low-cost alignment
systems and position sensors for segment phasing. Feasibility
study for serial production and integration of thousands
of units. |
| 04300 |
Position actuators |
Objective: feasibility of nm-accuracy, cost-effective
segments position actuators.
Tasks: development and testing of actuators for
segment positioning (Wind Evaluation Breadboard #04800);
feasibility study for cost-effective serial production
& integration of thousands of units |
| 04400 |
Characterisation of image properties |
Objectives: quantify crucial system requirements
in relation to science goals.
Tasks: determination and specification of most
suitable parameters for the characterization of science
image contrast |
| 04500 |
High contrast imaging |
Objectives: identify and quantify extreme contrast
imaging techniques (mainly for exo-planet imaging and
spectroscopy).
Tasks: review, development of high contrast imaging
methods. Performance evaluation through simulations; implications
on system / subsystems specifications |
| 04600 |
Active Phasing Experiment (APE) |
Objectives: testing of control strategies and
techniques.
Tasks: design, construction, laboratory and on-sky
testing of a technical instrument emulating active wavefront
control functions, including three distinct on-sky phasing
techniques |
| 04800 |
Wind Evaluation Breadboard (WEB) |
Objectives: quantify ability to cope with high
frequency wind disturbances.
Tasks: Construction and on-site testing of the
wind effect at ORM, Canary Islands of a bench emulating
7 segments, including support systems and support structures |
