Abstract
A laser crosslink apparatus includes an optical device (212, FIG. 5), a beam splitter (512), an acquisition channel and a tracking and communication channel. The acquisition channel includes a high density optical fiber bundle and an acquisition channel device (510). The optical device (212) receives laser light from a wide field of view, and the beam splitter (512) splits the light into the two channels. The high density optical fiber bundle (204) has one end (206) in a focal plane of the optical device, and another end (208) coupled to the acquisition channel device (510). The acquisition channel device (510) includes an optical receiver array (400, FIG. 4). The location of spot footprints on the optical receiver array determines the direction from which the laser light is received within the wide field of view. The optical fiber bundle allows the optical receiver array to be located away from the optical device, near the receiving/tracking system, where it can be more easily shielded from the harmful effects of space.
