Modification of the Naval Postgraduate School Lidar System
type: CreativeWork
description: The Naval Postgraduate School (NPS) Lidar System was modified to allow comparison of lidar profiles with radiosonde profiles preparatory to evaluation of the lidar as a monitor for changes in the boundary layer. The detector package was modified to permit day and night operation and to reduce the overlap-limited minimum measurement range. Redesign of the transmitter beam expansion optics raised the power threshold for internal optics damage while improving the filling of the 18 output mirror and maintaining eye safe operation. Tests of the system on completion of modification demonstrated clear- air returns to ranges of 1 to 1.5 kilometers. Direct comparison of clear-air lidar returns with radiosonde balloon launches can now be undertaken to evaluate correlation of changes
