IDS Sensors PAGE 213 1 Real-time stage guiding accuracy analysis 4 Bearing errors detection with contact-less probe Monitor your stage guiding accuracy in real time. With an angular tolerance exceeding several degrees, the IDS3010 can sense erratic pitch and yaw motions. A simple closed loop regulation may then control the carrier displacement within 6 degrees of freedom. The IDS3010 cost -effectiveness and compact design allow integration in industrial systems as a set-and-forget sensor. Indeed, interferometry intrinsically eliminates the need for time-consuming system recalibration. 2 In-situ live machine vibrometry Diagnose your parts' vibrations instantaneously. The IDS3010 electronics performs a live Fast Fourier Transform (FFT) of the part displacement. It enbales accurate, non-contact frequency analysis with a bandwidth from DC to 10 MHz. Its modular and portable design perfectly fits quality control applications and allow on-the-fly diagnosis of a machine directly in the production line. Moreover, its interface uses industry standards for easy integration. 3 Characterize the error motions of your bearings. Depending on the probe in use, the IDS3010 tolerates even curved and milled surfaces as target. Therefore, users can monitor the motion at the exact location of interest. For example, it can directly measure the actual runout of a rotating shaft and avoids any in between errors sources such as stage bearing imperfection (Abbe error) or slight angular encoder misalignment. 5 High velocity & ultra precision motion tracking Track fast stage displacement with ultimate accuracy. In standard operation, the IDS3010 detects a target's relative displacement over range exceeding 5 m with sub-nanometer resolution. Its real-time electronics outputs linear stage motion with velocities up to 2 m/s. The sensor's compact and ergonomic design eases integration in OEM setups and grants use of this state of the art device even to non-specialists in interferometry. In-situ live workpiece vibration analysis Analyse directly your workpiece vibrations. The IDS3010 can recover in-plane motion of a rotating milling machine workpiece. For example, users can measure the difference in vibration spectra arising when the milling process takes place as compared to the idle state. This crucial information enables fine control of the machine tool in order to eliminate contour errors or bad surface finish. This in turn improves part quality and higher production throughput. attoSENSORICS Ultra Precision Sensors
