Abstract

Laser-telescope alignment is a key factor in a lidar system, and its setup determines the lidar signal quality. Procedures to accomplish this task may vary depending on the operator, from detailed step-by-step procedures to visual inspection of particular behavior of the lidar signal. No matter the method used, it should be performed by an expertised lidar operator in order to preserve the lidar quality signal. In this work, a software to aim the alignment procedure is presented. With a clear interface, it helps the lidar operator to approach the right alignment state based on a live Rayleigh-Fit applied to the acquired lidar signal. Also, a quantitative result of this alignment is shown, giving to the operator a visual during the alignment procedure. Main features of the tool and working scenarios are presented.
