Making the unmodulated Pyramid wavefront sensor smart
Making the unmodulated Pyramid wavefront sensor smart is a scholarly work by Laird M. Close, published in 2024 in ''Astronomy and Astrophysics''. The main subjects of the publication include optics, wavefront, physics, pyramid, wavefront sensor, Strehl ratio, nonlinear system, adaptive optics, sensitivity, and computer science. The authors show that the authors' nonlinear reconstructor has a dynamic range of >600 nm root-mean-square (RMS), significantly outperforming the linear reconstructor that only has a 50 nm RMS dynamic range.
