  1. Improving Accuracy Of Long Travel Linear Positioning Stages With Error Mapping

    A linear encoder can be used to significantly improve the accuracy and repeatability of stepper or servo-motor positioning stages, but even the high-end linear encoders have linearity errors. To reduce these errors, a laser interferometer measures them and uses a motion controller with the capability to store a dynamic error map.

  2. Hexapod For Drone Testing: 6 Axis Motion Simulator To Improve Image Stabilization

    Analog and digital image recording technology has always been bombarded by motion and vibration. Techniques for compensating for unwanted motion include electronic algorithms and active opto-mechanical motion compensation systems. This article presents methods for using hexapod 6-axis motion systems for reducing image blur from a drone due to vibrations.

  3. Piezo Flexure Nanopositioning Stages: Frequently Asked Questions

    PI offers many types of nanopositioning stages - positioning devices capable of nanometer or sub-nanometer resolution -  such as air bearing stages, linear motor stages, and magnetic levitation stages. This blog article covers a list of frequently asked questions regarding nanopositioning stages, and includes in-depth answers on each topic.

  4. Motion Control And Precision Positioning In Vacuum Environments

    Vacuum applications, and technologies that can only be applied in vacuum or cryogenic environments have grown in importance within scientific research and industry applications. Optics technologies use vacuum environments to manufacture components such as fiber laser optics and sensitive detectors. Other applications that use vacuum environments include small epitaxy processes, semiconductor manufacturing, and X-ray or UV applications.

  5. Precision Motion And Positioning Solutions For High Vacuum And UHV Catalog

    The design principles for vacuum-compatible positioning systems include selecting suitable materials, handling, assembling, and testing conditions, and quality control. This catalog covers the technologies and product solutions for high vacuum and UHV applications in scientific research and industrial production.

  6. Patterned Force Generation – A Precise Touch In The Time Domain

    Devices with touch-sensitive interfaces not only sense pressure, but are position-sensitive and force-sensitive. Producing devices with touch-sensitive interfaces requires highly precise test equipment with the ability to repeatedly generate fine-grained motions of exacting force and time profiles. The V-273 family of voice-coil actuators, coupled with the C-413 digital controller, offers developmental and test engineers the perfect tool for quantitatively qualifying touch-enabled devices.

  9. Super-Resolution Optical Microscopy, Nanoscopy, And Nanopositioning Motion Control

    This article presents the new frontier for super-resolution optical microscopy, nanoscopy, and nanopositioning motion control.

  10. PI Mini Imaging Drives For Endoscopy

    With the aim to cause patients as little discomfort as possible, minimal invasive surgery (MIS) techniques use endoscopes integrated with a miniature drive to achieve variable focusing so that objects can be in sharp focus at all times. These endoscopes are used in larynx diagnostics or laparoscopy where optics and special instruments can then be introduced to the abdominal cavity through working trocars. Patients will then experience less post-operative pain and are able to be discharged earlier from the hospital. This application note describes the focus and zoom control functions within these miniature drives, and provides information on available PI piezo miniature drives for endoscopy applications.
