A time-division correction method for adaptive optics system

An adaptive optics system can measure and compensate the wavefront distortion caused by dynamic disturbance in real time. It is usually used for astronomical observation and other occasions. According to the current technology, it is only suitable for small field of view optical system or point target, but not for ground extended target detection. In order to solve this problem, a correction method is proposed: firstly, the sub aperture image of wavefront sensor is divided into several sub regions, each sub region corresponds to a certain light direction or field angle range; secondly, calculate the offset of the image feature points in each sub region, and an image with good correction effect in a field of view in this direction is obtained; the last step is to measure each sub region one by one and combine these images into a full frame image. Through comparison, it is found that the method proposed in this paper is essentially to divide the extended target into multiple point light sources for correction.

OPPORTUNITIES TO USE NEW ROBOTIC TELESCOPES IN SPAIN

The Space Exploration Ltd (SEL) has established new observatory facilities in Spain to provide the opportunity for astronomers to remotely access a range of research-grade telescopes and access to a spectrograph, polarimeter, photometry and adaptive-optics system. In the future, simultaneous automated multi-wavelength observations will also be tested and made available. This will enable the development of new observational and analytical processes for astronomy and astrophysics. Observations will be scheduled via Internet, including projects requiring long-term ongoing monitoring. Data can be accessed rapidly following scheduled observations. Access is on a commercial, non-competitive basis, avoiding conventional time-consuming administrative requirements, wait times, and disappointments.
