I'm going to use a Single-Point Long-Distance LiDAR which gives me information about distances from the laser to natural objects (i.e. a wall). Its detection angle is 0.5° so it behaves very different from the usual laser scanners used with ROS.

Should I be able to obtain a /laser/scan topic with limited information, or won't it work at all? According with this ROS tutorial, I should be able to receive information only on range_min and range_max with all the other values set to NULL, is it correct?
