3D Scanner Selection Guide

LMS - Z420i

Principle of Operation

The range finder electronics (1) of the 3D scanner RIEGL LMS-Z420i is optimized in order to meet the requirements of high speed scanning (fast laser repetition rate, fast signal processing, and high speed data interface).

The vertical deflection ("line scan") of the laser beam (2) is realized by a polygon (3) with a number of reflective surfaces. For high scanning rates and/or a vertical scan angle q up to 80°, the polygonal mirror rotates continuously at adjustable speed. For slow scanning rates and/or small scanning angles, it is oscillating linearly up and down. The horizontal scan ("frame scan") is provided by rotating the complete optical head (4) up to 360°.

Scandata: RANGE, ANGLE, SIGNAL AMPLITUDE, and optional TIMESTAMP are transmitted to a laptop (6) via TCP/IP Ethernet Interface (5). Camera (7) data are fed into the same laptop via USB/firewire interface (8).

The RiSCAN PRO software (9) allows the operator to perform a large number of tasks including sensor configuration, data acquisition, data visualization, data manipulation, and data archiving. RiSCAN PRO runs on platforms WINDOWS XP and 2000 SP2.
