The RIEGL LMS-Q120ii 2D - laser scanner provides accurate non-contact line scanning using a narrow infrared laser beam. The instrument makes use of the precise time-of-flight laser range measurement principle and of fast line scanning by means of a high-speed opto-mechanical scan mechanism, providing fully linear, unidirectional and parallel scan lines.

The rugged overall system design makes the RIEGLLMS-Q120ii exceptionally well suited for installations in harsh industrial environment, it is specially designed for long-term operation without the necessity of frequent maintenance. The instrument needs only a single supply voltage and provides line scan data via its integrated TCP/IP Ethernet interface. The binary data stream can easily be decoded by user-designed software using the available software library.
