PCI-Bus for Nanopositioning Controllers: Why it Matters
Many of today's high-tech applications, such as imaging, metrology, scanning microscopy and surface analysis require a combination of high-speed motion control and high-resolution vision. They also require extremely fast data acquisition and precise synchronization between the imaging and motion control devices. Peripheral components with PCI bus interface are ideal for achieving these tasks, because the PIC-bus was designed to give high-bandwidth access to the microprocessor in the PC. PI has now introduced the worlds first commercially available, fully digital piezoelectric nanopositioning controller on a PCI board. The PCI allows for very fast communication and easy integration with devices such as frame grabbers-a definite plus in real-time data acquisition applications or when operating multiple controllers simultaneously.

Additional High-Bandwidth Analog Interface
The E-761 boasts a high-bandwidth analog position control input in addition to its PCI interface. This is ideal for applications where position data are provided in analog form and for external triggering tasks.

Active Trajectory Control Provides Sub-Nanometer Motion Accuracy
Incorporating a powerful 32-bit DSP, the E-761 controllers offers advanced features such as polynomial linearization and coordinate transformation-not available in conventional controllers. With flexible coordinate transformation, sensor and actuator axes need not be parallel to each other and rotation can be added to a single module XY-motion system, or tilt errors can be reduced for motion accuracies in the sub-nanometer range.

No External Power-Amplifiers Required: Drivers on Board
The E-761 incorporates highly linear 24-bit digital analog D/A converters driving four on-board, low-noise piezo drivers, thus eliminating the need for additional external amplifiers.

Plug & Play Auto-Calibration for Interchangeability of Positioning Systems
E-761 digital piezo controllers automatically recognize ID-chip equipped nanopositioning stages and optimize all servo-control parameters accordingly.

Digital Linearization for Improved Accuracy
In order to achieve the highest degree of linearity over the entire travel range, the E-761 uses a number of innovative techniques: A hardware-based system in the sensor-processing electronics known as ILS (Integrated Linearization System) and a firmware-based system that uses polynomial linearization for the entire electronics and mechanics sections.

Extensive Software Support
The controller comes with a large variety of software tools, LabView(TM) drivers and Windows® DLL's for easy setup, system optimization and integration in application-specific programs.
