Abstract
The ACASS 3D LIDAR system operates in a fundamentally new manner combining features of flash LIDARS and scanning LIDARS simultaneously which enables mission and performance trades to be conducted by varying the sizes of illumination patches within the scenes being observed. Further the combination of these modes of operation into a single LIDAR system enables multiple modes of operation and multiple missions to be accomplished with single lasers obviating the need for multiple lasers and enabling significant simplification of beam control modes. Systems which result from the new, expanded size, weight, power, cost trade space enabled by the ACASS concept can provide new levels of performance at significantly reduced risks and costs The achievement of wide area, three dimensional imaging using a LIDAR sensor system is accomplished with one laser which operates using an eye safe fiber laser with very high puke 13 rates but very low energy per pulse.
