ABSTRACT:
Originally developed by astronomers to correct the effect of atmospheric turbulences, Adaptive Optics (AO) has now become a common tool to correct optical aberrations, dynamic or static, in a wide range of optical systems. In Ultrafast and Intense Lasers for example, using AO, large gains in maximum peak energy could be obtained at the focal spot by correcting aberrations induced by both optical components and thermal effects in amplifiers. Today, AO is also making a ground-breaking contribution into the field of biomedical imaging. It is a success story in ophthalmology for correcting eye aberrations in retinal imaging systems and it is foreseen as an undeniable tool in many light microscopy techniques for the compensation of large aberrations induced by biological tissues.
This presentation will describe a typical adaptive optics solution based on a Shack Hartman wavefront sensor, a deformable mirror and control software. Several examples of implementation of AO systems on high energy lasers and non-linear microscopy will be shown and discussed. A full AO system, including a HASO 3 sensor, a MIRAO 52 deformable mirror and the CASAO control software will be demonstrated during this talk.
BIOGRAPHY:
Philippe Clemenceau is managing the Axiom Optics Division of Imagine Optic Inc., a small company located in Cambridge, MA. He received his Master’s degree in Optical Sciences from the Institute of Optics Graduate School of Orsay, France in 1998.
P. Clemenceau was a visiting researcher at CREOL (Orlando) from Jan
1999 to June 2000 under the direction of Ron Philips, then Aristide Dogariu. He worked in research and development at Thales Optronics (Guyancourt, FR) on laser radars and at Alcatel Optronics (Nozay, FR) on fiber amplifiers. From 2002 to 2009, he was the sales director and co-founder of Bossa Nova Technologies, a small company based in Los Angele (CA) developing high frequency vibrometers for Non-Destructive Testing and polarization imaging systems for skin applications. His interests are in imaging, adaptive optics, microscopy, laser diagnostics and laser vibrometry. He is the co-author of 2 European patents on polarization imaging.
