Presentation
Image has become an important tool for communication and scientific knowledge. When passing through distorting and turbulent media, Light waves and therefore images are distorted and blurred.
Since several years, the adaptive optic has become an essential component for Wave Front Correction, and has found numerous applications in astronomy, military observation, correction of scientific and industrial laser beams, and in medical imaging, especially in ophthalmology.
Principle
An Adaptive Optics system is a device which corrects, in real time, perturbed optical wavefronts. It is composed of :
An analyzer which measures the wave deformation.
A deformable mirror which corrects the wavefront.
A computer which drives the mirror with informations coming from the analyzer.
CILAS develops, manufactures and sells deformable mirrors based on the piezoelectric effect.
The technological choices of CILAS offer the following advantages :
A large stroke enabling the correction of deep deformations (several wavelengths).
A high speed of several kilohertz.
A high surface quality compatible with laser beam correction.
A low power consumption.
A great working stability over a wide range of temperatures (-5 °C à 25 °C).
A high reliability. |
