Abstract

The present invention relates to an improved method and a LIDAR system comprising an emitter for emission of a coherent electromagnetic EM signal and a transmitting optical arrangement configured to transmit the electromagnetic signal towards a measurement area. By the method and system, detection of both the polarized and depolarized backscattered EM signal is obtained, whereby an improved signal-to-noise ratio is obtained.
