The Single Pixel Feed Receiver (SPFRx) is a Sub-Element of the Square Kilometer Array (SKA) Dish Element. Its main function is receiving RF signals captured by the SKA-mid Dish (DSH) and pre-amplified by the Single Pixel Feed (SPF) Sub-Element compon

Phased array feeds (PAFs) are an active research area in radio astronomy, as they offer potential advantages over traditional single-pixel feeds. Their key advantage is increased field of view and survey speed, however they also permit tailoring the

With two large deformable mirrors with a total of more than 7000 actuators that need to be driven from the measurements of six 60x60 LGS WFSs (total 1.23Mpixels) at 800Hz with a latency of less than one frame, NFIRAOS presents an interesting real-tim
