2D Mobile Laser Scanners

The range finder electronics of the 2D laser scanner RIEGL VQ-180 are optimized in order to meet the requirements of high speed scanning (high laser pulse repetition rate, fast and highly accurate digital signal processing, and versatile interfacing).
 
The vertical deflection ("line scan") of the laser beam (1) is realized by a polygon (2) with a number of reflective surfaces. For high scanning rates and/or a vertical scan angle (theta) up to 100°, the polygonal mirror  continuously rotates at adjustable speed. 

The instrument is configured and operated by a laptop (3). Scandata, consisting of RANGE, ANGLE, SIGNAL AMPLITUDE, and optional TIMESTAMP is either stored locally on the instrument or transmitted to the operating laptop via TCP/IP Ethernet Interface (4).

The range finder electronics of the 3D laser scanner RIEGL VQ-250 are optimized in order to meet the requirements of high speed scanning (fast laser pulse repetition rate, fast and highly accurate digital signal processing, and versatile interfacing).

The deflection of the laser beam (1) is realized by a rotating mirror (2) with a full 360° field of view at a rate of 100 scans per second.

The instrument is configured and operated by a laptop (3). Scandata, consisting of RANGE, ANGLE, SIGNAL AMPLITUDE, and optional TIMESTAMP is either stored locally; or on a USB storage device attached to the instrument (4); or transmitted to the operating laptop via TCP/IP Ethernet Interface (5).
