This report compares the heterodyne reception mixing efficiency of a laser radar employing a conventional Free-Space mixer to one employing a fiber mixer. A rigorous derivation for speckle targets shows the two mixing schemes will have approximately the same mixing efficiency. The fiber mixing efficiency is optimized by choosing the optics numerical aperture NA equal to the fiber NA. Laser radar, Heterodyne detection, Coherent detection, Fiber mixers.
