Current image-based wavefront sensing approaches rely on post-processing techniques to return an estimate of the aberrated optical wavefront with accuracies to the nanometer level. But the lag times between wavefront sensing, and then control, contributes to a significant latency in the wavefront sensing implementation. In this analysis we demonstrate accelerated image-based wavefront sensing performance using multiple digital signal processors (DSP's). The computational architecture is discussed as well as the heritage leading to the approach.\u003c\/p\u003e","brand":"Bibliogov","offers":[{"title":"Paperback","offer_id":45154843459735,"sku":"9781289286484","price":1074.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781289286484.webp?v=1767300408","url":"https:\/\/atlanticbooks.com\/products\/wavefront-sensing-via-high-speed-dsp-9781289286484","provider":"Atlantic Books","version":"1.0","type":"link"}
