RegisterSpatial signal, optic signal, elementary spatial signalSpatial signal (or optic signal) is transmitted by electromagnetic wave. Information is not stored in time course of field intensity but in the amplitude distribution of field intensity in the transversal plane (perpendicular to the direction of propagation): E = E( x, y), z denotes direction of propagation. Amplitude distribution of elementary spatial signal is harmonic in one direction and is constant in another direction. Back
