+\section dense_laser_assembler
+\b dense_laser_assembler Aggregates laser data very similarly to the
+point cloud assembler. However, the output data structures are very
+different. Instead of defining each laser ray as an XYZ point with an
+intensity, the dense_laser_assembler instead uses multiarrays to store
+the scans in a dense representation.
+
+Intensity and Range data are each stored in their own Float32
+multiarray. Each row of the multiarray is a scan, and these rows
+are stacked (sorted by the tilting angle) to form the 'rasterized'
+dense representation.
+
+Meta information is also stored along with the range and intensity data.
+The tilting angle of the hokuyo is published as another multiarray. And
+the laser's configuration params are also published. This then provides
+us enough information to fully determine the location and time of any
+laser ray in the dense representation.
+
+\section laser_image_node
+laser_image_node converts the intensity and range multiarrays into
+uint8 ROS images that can be viewed with image_view. This can often
+be a very useful debugging tool to make sure that the dense scans
+look reasonable.
