Sid4 adaptive optic
WebAdaptive optics (AO) is a technique that removes the atmospheric disturbance and allows a telescope to achieve diffraction-limited imaging from the ground. This is critical in achieving the maximum S/N given in equation (1).The basic idea of AO is to first measure the amount of atmospheric disturbance, then correct for it before the light reaches the camera. WebMar 17, 2024 · Guiding and Wavefront Sensors. Essentially all observations with the Gemini telescopes require the use of either a peripheral wavefront sensor (PWFS) or an on-instrument wavefront sensor (OIWFS) assigned to a star near the science target, and in some cases an adaptive optics wavefront sensor (AOWFS) assigned to a star or artificial …
