  • Abstract
    A wave optics computational procedure to obtain optimally selective excitation in d.m.d. and d.m.a. measurements is presented. Good agreement with a Fourier optics approach is found. It is shown that for the optimal excitation of higher order mode groups (by increasing input beam offset) the beam spot size must be considerably reduced from that for the optimal excitation of the fundamental mode.
