A new edge detection technique based on iodine molecular absorption cells is proposed. This technical path has the advantages of signal intensity detection independent of incident angle, fast measurement speed, not being easily affected by laser intensity jitter, and not requiring salinity information. It is expected to be used on airborne, spaceborne, and other large mobile platforms, and it has a promising future application.
