A 4096 Element Continuous Facesheet MEMS Deformable Mirror for High-Contrast Imaging

This paper presents the progress in the development of a 4096 element MEMS deformable mirror, fabricated using polysilicon surface micromachining manufacturing processes, with 4μm of stroke, a surface finish of less than 10nm RMS, a fill factor of 99.5%, and bandwidth greater than 5kHz. The packaging and high speed drive electronics for this device, capable of frame rates of 22 kHz, are also pr...

Development of a 4096 Element MEMS Continuous Membrane Deformable Mirror for High Contrast Astronomical Imaging

Presented in this paper is the development of a 4096 element continuous membrane deformable mirror under development for the Gemini Planet Imaging instrument designed for extra solar planet detection. This deformable mirror will enable the next generation of adaptive optics (“Extreme” AO) capable of achieving contrasts of up to 10, required to detect these planets that are obscured by the brigh...

Two-Mirror Apodization for High-Contrast Imaging

Direct detection of extrasolar planets will require imaging systems capable of unprecedented contrast. Apodized pupils provide an attractive way to achieve such contrast but they are difficult, perhaps impossible, to manufacture to the required tolerance and they absorb about 90% of the light in order to create the apodization, which of course lengthens the exposure times needed for planet dete...

MEMS Deformable Mirror Actuators with Enhanced Reliability

MEMS deformable mirrors with thousands of actuators are under development for space-based operation, which require fault tolerant actuators that will not fail due to electrical overstress. We report on advances made in the development of MEMS deformable mirror actuators with enhanced reliability for space-based, high-contrast imaging instrumentation that eliminate irreversible actuator damage r...
