Adaptive Optics
Adaptive optics is a new technology which is being used now a days in ground based telescopes to remove atmospheric tremor and thus provide a clearer and brighter view or image of star seen through the ground based telescopes.
- Starlight travels millions of light years across the vacuum of space only to get distorted by our atmosphere in the last 150 miles before reaching Earth.
- To compensate for the atmosphere, Adaptive Optic Systems use a Deformable Mirror to correct the incoming light.
- A Deformable Mirror is a reflective device that can change its shape quickly, in real-time.
- Special cameras, called Wave Front Sensors, measure the atmospheric disturbance.
- This information is sent to a fast computer, which calculates the shape to apply to a special "deformable mirror”.
