Segmented bimorph mirrors for adaptive optics: segment design and experiment.
نویسندگان
چکیده
We discuss the concept of lightweight segmented bimorph mirrors for adaptive optics. The segment consists of a monocrystal silicon substrate actuated by an array of in-plane piezoceramic (PZT) actuators with honeycomb electrodes. We focus on technological aspects of the segment design that are critical for space applications and describe a single segment demonstrator. The morphing capability of the segment is evaluated experimentally. We also discuss the local deformations (dimples) associated with the shape of the electrodes acting on the PZT array.

Comparative analysis of deformable mirrors for ocular adaptive optics.
We have evaluated the ability of three commercially available deformable mirrors to compensate the aberrations of the eye using a model for aberrations developed by Thibos, Bradley and Hong. The mirrors evaluated were a 37 actuator membrane mirror and 19 actuator piezo mirror (OKO Technologies) and a 35 actuator bimorph mirror (AOptix Inc). For each mirror, Zernike polynomials and typical ocula...
متن کاملFabrication and Characterization of Mems Deformable Mirrors for Adaptive Optics
A bimorph deformable mirror (DM) for use in ophthalmologic adaptive optics is presented. The fabrication process and the results of characterization of the DM are described. Interferometric measurements of the DM surface shape and voltage-to-displacement characteristics are shown. The response of the DM to a step voltage input is measured using a commercial laser Doppler vibrometer (LDV). Exper...
متن کاملCreating flat-top X-ray beams by applying surface profiles of alternating curvature to deformable piezo bimorph mirrors
Beam shaping is becoming increasingly important for synchrotron X-ray applications. Although routine for visible light lasers, this is challenging for X-rays due to the limited source coherence and extreme optical tolerances required for the shaping mirrors. In deliberate defocusing, even surface errors <5 nm r.m.s. introduce damagingly large striations into the reflected beam. To counteract su...
متن کاملCharacterization of a next-generation piezo bimorph X-ray mirror for synchrotron beamlines
Piezo bimorph mirrors are versatile active optics used on many synchrotron beamlines. However, many bimorphs suffer from the `junction effect': a periodic deformation of the optical surface which causes major aberrations to the reflected X-ray beam. This effect is linked to the construction of such mirrors, where piezo ceramics are glued directly below the thin optical substrate. In order to ad...
متن کاملEfficient testing of segmented aspherical mirrors by use of a reference plate and computer-generated holograms. II. Case study, error analysis, and experimental validation.
Segmented mirrors present unique challenges to fabrication and testing that are absent for monolithic optics. Since traditional asphere tests do not address segmented optics adequately, we validate a previously developed method to test large quantities of segments accurately, quickly, and economically. In this test, the aspheric shape of each segment is controlled to high accuracy by use of com...
