Large sparse aperture telescope wavefront sensing and control via pretrained neural network with attention module [PDF]
Scientific ReportsThe ability to detect pistons with high accuracy over a wide range is paramount to the co-phasing of sparse aperture optical systems. This paper proposes a global piston error modulation method for sparse aperture mirrors based on convolutional neural ...

An Efficient Correction Algorithm for Eliminating Image Misalignment Effects on Co-Phasing Measurement Accuracy for Segmented Active Optics Systems. [PDF]
PLoS ONE, 2016 The misalignment between recorded in-focus and out-of-focus images using the Phase Diversity (PD) algorithm leads to a dramatic decline in wavefront detection accuracy and image recovery quality for segmented active optics systems.

Coarse Phasing Detection Using Multiwavelength Wavefront
Photonics, 2023 Presently, the segmented mirror is the mainstream development direction of large-aperture telescopes. The key problem affecting the performance of segmented mirror telescopes concerns the co-phase of the segments. The segments’ co-phase includes the fine

A co-phase matrix to guide simultaneous multithreading simulation [PDF]
IEEE International Symposium on - ISPASS Performance Analysis of Systems and Software, 2004, 2004 Several commercial processors have architectures that include support for simultaneous multithreading (SMT), yet there is still not a validated methodology for estimating the performance of an SMT machine that does not rely on full program simulation.
