A magnetic liquid deformable mirror for high stroke and low order axially symmetrical aberrations [PDF]
, 2006 We present a new class of magnetically shaped deformable liquid mirrors made of a magnetic liquid (ferrofluid). Deformable liquid mirrors offer advantages with respect to deformable solid mirrors: large deformations, low costs and the possibility of very

Calibration of Deformable Mirrors for Open-Loop Control. [PDF]
Sensors (Basel), 2022 Deformable mirrors enable the control of wave fronts for the compensation of aberrations in optical systems and/or for beam scanning. Manufacturers of deformable mirrors typically provide calibration data that encode for the fabrication tolerances among ...

Wavefront sensing with a brightest pixel selection algorithm [PDF]
, 2011 Astronomical adaptive optics systems with open-loop deformable mirror control have recently come on-line. In these systems, the deformable mirror surface is not included in the wavefront sensor paths, and so changes made to the deformable mirror are not ...

Suppressing low-order eigenmodes with local control for deformable mirrors [PDF]
, 2012 To improve the mechanical characteristics of actively controlled continuous faceplate deformable mirrors in adaptive optics, a strategy for reducing crosstalk between adjacent actuators and for suppressing low-order eigenmodes is proposed.

Characterization of a Deformable Mirror for astronomical applications [PDF]
, 2023 openI will demonstrate the compensation of a perturbed wavefront through the utilization of a deformable mirror. This involves an exploration of the modal framework and the decomposition of a wavefront using Zernike polynomials.

Phase control of a longitudinal momentum entangled photon state by a deformable membrane mirror
, 2009 We propose a paradigmatic demonstration of the potentialities of a deformable mirror for closed-loop control of a two-photon momentum-entangled state, subject to phase fluctuations.

Bi-photon propagation control with optimized wavefront by means of Adaptive Optics
, 2012 We present an efficient method to control the spatial modes of entangled photons produced through SPDC process. Bi-photon beam propagation is controlled by a deformable mirror, that shapes a 404nm CW diode laser pump interacting with a nonlinear BBO type-
