Mirror Actuators in Telescope Applications
As discussed in previous posts, large telescopes today use a segmented mirror approach due to the deformation of mirrors larger than 5m. To this end, mirror actuators become a critical component of telescope design. A long-time National Instruments partner, Physik Instrumente uses nanopositioning techniques to provide 6 degrees of freedom control on the mirrors. Mirror actuators are critical as they represent a large portion of the failures in existing actuators.
The TMT telescope which stands for Thirty Meter Telescope solves the problem by shrinking the individual mirror size down to 1 foot and then applying many more actuators to the mirror to deform the shape to correct for atmospheric conditions.

Your article is amazing. It helped me a lot with my research about different kinds of valves and
actuators and how this stuff works with other mechanical devices...
again,thanks a lot.

Thank you for the informative post, Hall.
Astronomical applications are one of our most important and fascinating business segments. From six-DOF positioning of secondary optic packages, to resolution-enhancing focal plane dithering, to the high-force/high-dynamics nano-actuators for deformable mirrors that caught your eye ...and much else... we enjoy quite a lot of immersion in this field. I've found that a robust LabVIEW library and support of LabVIEW FPGA can be must-have tools for our mutual customers.
Happy Thanksgiving! We appreciate the reference.
