Adaptive optics is a method where systems immediately correct the wavefront of incoming light which is disturbed by atmospheric fluctuations. This atmospheric turbulence can move the incoming light (think of stars twinkling) and therefore blur an image on a sensor. Adaptive optics allow astronomers to correct this and obtain the clearest image at the performance limit of the telescope. In order to perform real-time and highly accurate wavefront correction, a camera in this application must have high speed and high resolution. In addition, since the wavefront correction is performed in a very dark state using a laser artificial star, the camera also needs high sensitivity.

For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website.

Cookies do various jobs which make the visitor’s experience of the internet much smoother and more interactive. For instance, cookies are used to remember the visitor’s preferences on sites they visit often, to remember language preference and to help navigate between pages more efficiently. Much, though not all, of the data collected is anonymous, though some of it is designed to detect browsing patterns and approximate geographical location to improve the visitor experience.
