Major new technologies in ALS70 Point Density Multiplier doubling productivity Multiple scan patterns new range counting circuitry Pulse rates closer to speed of light limit for given flying height (all models) Dual-output scanner doubles effective pulse rate and scan rate (ALS70-CM and ALS70-HP only) Laser output split into two beams (slight forward/rearward look) Dual receivers Autoscan feature monitors flying height and speed over ground & adjusts scan rate to help to keep scan patterns out-of-phase with one another Multiple scan patterns (sine, triangle and raster) for greater flexibility Increased receiver bandwidth and dynamic range, for better detection of small and/or low-reflectivity surfaces (e.g., power lines, fresh asphalt) 37
