Abstract

The differential measurement system has a source mechanism (1) and luminous beam (2) outputs. There is a superposition mechanism (5) and an analysis mechanism (6). Two antennas (A1,A2) outputs modulate (3) the light source, and the analyzer determines the differential propagation direction. Independent claims are also included for differential measurement method and system/method for determining direction of propagation of a wave in a network of antennas.
