Introduction to the Center for Adaptive Optics Winter 2003
2/15 What is Adaptive Optics? Adaptive Optics (AO) refers to optical systems which adapt to compensate for optical effects introduced by the medium between the object and its image. In Astronomy: –AO technology can remove the blurring/twinkling effect of the Earth's atmosphere that has long plagued ground-based astronomers. –It allows ground-based telescopes to achieve image clarity previously attainable only by space-based instruments. In Vision Science and Ophthalmology: –AO makes it practical for scientists to study individual photoreceptors in the retinas of living human eyes. Without AO, the eye’s lens and cornea distort images of the retina, making it impossible to study individual cells on the retina. –In addition, AO can help ophthalmologists make better glasses and contacts, and improve overall diagnosis/study of eye diseases.

5/15 What is the Center for Adaptive Optics? The CfAO is one of 5 National Science Foundation “Science and Technology Centers” started in Fall 1999. –Funded by NSF for 5 years (through 2004) at ~$4 million per year, and renewable for an additional 5 years (through 2009). CfAO’s Purpose: –To advance and disseminate the technology of adaptive optics in service to science, health care, industry, and education. CfAO’s Goal: –To lead the revolution in AO, by developing and demonstrating the technology, creating major improvements in AO systems, and catalyzing advances nationwide within the next decade.
6/15 CfAO’s Research Themes Theme 1 - Education and Human Resources –Increase interest and knowledge of CfAO activities in broader community. –Professional development of graduate students and postdoctoral researchers. –Promote increased participation, retention, and advancement of underrepresented high school and college students in Science, Math, Engineering and Technology careers. Theme 2 - AO for Extremely Large Telescopes –Complete AO system design for the next generation of large telescopes (30- 100 meters in diameter). Key technologies: Laser guide stars, Multi-conjugate AO Theme 3 - Extreme Adaptive Optics –Advanced AO systems optimized for ultra-high contrast astronomical imaging of extra-solar planets and planetary systems. Key technologies: Coronographs, Wavefront Sensors Theme 4 - Compact Vision Science Instrumentation –Develop compact AO imaging instruments for mainstream clinical and scientific use. Key technologies: MEMS Deformable Mirrors

9/15 “Center” Attributes Encourages technology transfer, knowledge sharing, and collaboration between vision science, astronomy, and engineering. Most CfAO member sites are equipped with videoconferencing equipment used for: –Casual meetings between members. –Remote auditing of graduate courses. –CfAO Executive Board meetings. –Event planning meetings. Supports building industry partnerships. Supports multi-site collaborations. Supports travel for members visiting other sites.
11/15 What is it? A paid, full-time 8-week program for interns to participate in ongoing research projects at various CfAO sites. Program includes orientation at UCSC during first week and student symposium at end of 8- week program. The program is for: –Community college students –Undergraduates from 4-year universities
12/15 What’s in it for you? Experience working with professors, researchers, and graduate students on cutting-edge research in astronomy, vision science, and engineering. Your own research project at a CfAO Institution. Involvement in a nationally recognized community of scientists. $2500 stipend, plus housing and travel expenses.
