How is the Still or Video Image Quality of Cameras Reliably Measured and Evaluated?

DxOMark Image Labs uses a PI hexapod to simulate camera movements in image stabilization testing

Taking sharp pictures despite poor lighting conditions, taking snapshots without blurring, recognizing traffic signs in driver assistance systems, or identifying dangerous situations in surveillance systems - all of this is possible today with the help of modern cameras. But how good is the still and video image quality of a camera or smartphone?

Hexapods Position ALMA Subreflectors and Compensate External Conditions

High-Precision ALMA Antennas are Decisive for the Success of the EHT

Sensation in astronomy: The Event Horizon Telescope (EHT), a worldwide network of eight radio telescopes, took the very first image of a black hole, which was published on April 10, 2019. Hexapods developed by PI play an important role in the ALMA telescopes on the Chilean plateau, which are part of the EHT.

Positioning Heavy Loads with Nanometer Precision over Long Travel Ranges

Is That Feasible?

Hybrid drives combine two different drive concepts into a high-performance and precision positioning system. They take advantage of both drives. These types of solutions are always in demand when one drive alone is not in a position to meet all of the requirements of applications. An example of this is nanometer-precision positioning of heavy loads over long travel ranges. Nanopositioning systems...
