Abstract

In recent years lidar (light detection and ranging) has made significant technical and theoretical advances. These advances have permitted the construction of a small, rugged, self-contained battery-operated lidar which measures visibility automatically without external inputs. This lidar measures cloud ceiling height and visibility from a single 1.06μm laser pulse with a modified AN/GVS-5 laser rangefinder. Since visibility and cloud ceiling height are measured, the lidar has been dubbed a visioceilometer.
