Abstract

The article considers the features of the optical and fiber-optic schemes of a pulsed coherent Doppler lidar. Two options for the telescope optical scheme design, as well as the use of an optical hybrid to increase the measurement range, are studied. The noise of the measuring system, which is determined by the active and passive components of the system, is analyzed. Experimental results are presented for the scheme with an optical hybrid and a basic scheme, as well as for a telescope based on spherical and aspherical optics.
