For high accuracy measurements, the NSI-OP-5929 Optical Measurement System (NSI Patent No.5,408,318) can be added to a large vertical or horizontal scanner to improve the probe position accuracy. This optional measurement system dynamically tracks probe X and Y positions in real time. The system also permits automated generation of probe X, Y and Z calibration error tables. The system uses laser interferometers for the X and Y position feedback, and a patented NSI optical subsystem for measuring the probe’s straightness.

The system uses laser interferometers for the X and Y position feedback, and a patented NSI optical subsystem for measuring the probe’s straightness. The NSI Antenna Measurement Software with built-in monitoring and calibration routines controls the optical system. The system includes NSI’s active position correction software, which uses the measured errors to actively move to a corrected position on the fly while acquiring near-field data (NSI Patent No. 5,419,631). The system consists of a NSI-OP-5930 Z-Laser, NSI-OP-5904 Z-Sensor, NSI-OP-5906A XY Optics Assembly , laser interferometers, and software.
