1. A system for initiating communication between two vehicles, the system comprising:
a transmitting vehicle sub-system comprising: an optical source;
an optical switching component configured to direct output from the optical source among an array of spatial positions in an output plane; wherein the switching component comprises a number of cascaded switchable transmission gratings; the number of cascaded switchable transmission gratings receiving an input beam from the optical source and routing the input beam to one spatial position from the array of spatial positions;
an infinite-conjugate imaging optical subsystem having a focal plane, said output plane being located at an image plane of the imaging optical subsystem; the infinite conjugate imaging optical subsystem imaging each spatial position from the array of spatial positions into a predetermined direction;
one or more detectors; and
a second wide-angle imaging optical subsystem; the second wide-angle imaging optical subsystem imaging a predetermined solid angle onto one of one or more detectors;
and a receiving vehicle sub-system comprising a retromodulator.
