This system consists of an acquisition camera, a fast-steering tip … WebThe GSMTs all plan to use pyramid wavefront sensors (PWFS) in ExAO instruments. The PWFS acts like a Foucault test in 2 dimensions. Light from the telescope is focused onto a glass pyramid tip where it is split and then the pupil plane is reimaged onto a detector.
A pyramid wavefront sensor is a type of a wavefront sensor. It measures the optical aberrations of an optical wavefront. This wavefront sensor uses a pyramidal prism with a large apex angle to split the beam into multiple parts at the geometric focus of a lens. A four-faceted prism, with its tip centered at the peak of the point spread function, will generate four identical pupil images in the absence of optical aberrations. In the presence of optical aberrations, the intensity distribution a… Webthe relationship between the wavefront phase aberrations (x;y )=2 w (x;y )= and the sensor signals. It can be shown that (Riccardi & Esposito, in preparation), for a square-based pyramid, the signals S x and S y depend 1 Sensor sensitivity refers to the ratio between the sensor signal rms and the incoming wavefront rms.
