Nanolaminate Deformable Mirrors [PDF]
IEEE/LEOS International Conference on Optical MEMS and Their Applications Conference, 2006., 2006 The paper describes two similar deformable mirrors that will demonstrate the feasibility of nanolaminate-based deformable mirrors over a wide range of size scales. Two complementary technologies: high-spatial-density electrostatic actuators and thin, flexible, lightweight nanolaminate foils are combined.

ADAPTIVE OPTICS WITH SEGMENTED MIRROR OR DEFORMABLE MIRROR
Le Journal de Physique Colloques, 1980 Two kinds of adaptive optics (COAT) are presented : one with segmented mirrors (COAT = 19) with 19 mirrors and actuators and the other with a continuously deformable mirror and 7 actuators. Each mirror of COAT 19 is moved by a piezoelectric actuator performing correction and modulation (dithering in the 12-24 kHz band).

Calibration of Deformable Mirrors for Open-Loop Control
Sensors, 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 ...

A Study on a Single Continuous Deformable Mirror for Correction of Atmospheric Disturbance [PDF]
한국정밀공학회지, 2018 The deformable mirror is the main component of the adaptive optical imaging system, which removes the atmospheric disturbance and acquires the target image without any loss and the beam transmission system, which transmits the laser beam to a long ...

Ultralightweight deformable mirrors [PDF]
Applied Optics, 2013 This paper presents a concept for ultralightweight deformable mirrors, based on a thin substrate of optical surface quality, coated with continuous active layers that provide separate modes of actuation at different length scales. This concept eliminates any kind of stiff backing structure for the mirror surface and exploits microfabrication ...

Photonics, 2023 Atmospheric turbulence causes refractive index fluctuations, which in turn introduce extra distortions to the wavefront of the propagated radiation. It ultimately degrades telescope resolution (in imaging applications) and reduces radiation power density

Stroke amplifier for deformable mirrors [PDF]
Applied Optics, 2004 We demonstrate a simple optical configuration that amplifies the usable stroke of a deformable mirror. By arranging for the wavefront to traverse the deformable mirror more than once, we correct it more than once. The experimental implementation of the idea demonstrates a doubling of 2.0 and 2.04 by two different means.
