1. A method of aerial surveying, comprising:
mounting an airborne LiDAR bathymetry system to an aircraft, wherein the airborne LiDAR bathymetry system comprises a receiver system, a detector system, and a laser transmission system comprising beam combiner optics, wherein the receiver system comprises an objective, a reflective aperture relay, a scanning wobble mirror, and a down-collimating telescope;
flying the aircraft at an altitude of at least around 10,000 feet;
emitting from the laser transmission system a first output beam at a first wavelength;
emitting from the laser transmission system a second output beam at a second wavelength, wherein the beam combiner optics align the first output beam and the second output beam; and
collecting data by the airborne LiDAR bathymetry system.
