Deformable mirror with thermal actuators
Optics Letters, 2002Low-cost adaptive optics is applied in lasers, scientific instrumentation, ultrafast sciences, and ophthalmology. These applications demand that the deformable mirrors used be simple, inexpensive, reliable, and efficient. We report a novel type of ultralow-cost deformable mirror with thermal actuators.

Beam correction of high power lasers often requires large wavefront deformations with very slow rates of change. Adaptive Optics Associates, Inc. (AOA) has developed a new type of deformable mirror in which thermal expansion of tubes control the mirror's figure. This paper is the subject of a patent disclosure.

Microelectromechanical deformable mirrors
IEEE Journal of Selected Topics in Quantum Electronics, 1999A new class of silicon-based deformable mirrors is described. These devices are capable of correcting time-varying aberrations in imaging or beam forming applications. Each mirror is composed of a flexible silicon membrane supported by an underlying array of electrostatic parallel plate actuators.

A mathematical model for a spherical hexagon mirror is described along with the model verifications. A flat hexagon epoxy mirror with aluminum core is used in test procedures in addition to a flat aluminum honeycomb mirror. Deformable reflector concepts are discussed and piezoelectric actuators are analyzed.
