An acquisition, pointing and tracking system for free space optical communications systems performs the pointing and tracking function internally by way of translating an internal optical fiber in the focal plane of the transceiver telescope with a reflecting mirror in the telescope focal plane of each linked transceiver. The beam reflected from the mirror records the exact direction of the reflected beam at the transmitting beam's transceiver terminal, providing the transmitting source to lock on to the receiving telescope, allowing for the link to be acquired.

Rapid acquisition, pointing and tracking optical system for free space optical communications

A beam steering apparatus and method for free space optical transceivers is disclosed. The beam steering function is performed internally by way of translating an internal optical fiber in the focal plane of the transceiver telescope using miniature micro-electro-mechanical systems (MEMS). The optical design of the transceiver provides a wide field of view and a pointing and tracking field of regard that is directly proportional to the translation of the optical fiber in the focal plane of the telescope. The apparatus and method can eliminate the need for external gimballing systems, and replace the gimballed free space optical beam steering function with MEMS that consumes very little power.

Apparatus and method for free space optical communications beam steering without gimbals

A targeting and tracking apparatus and method for optical transceivers is disclosed. The tracking function is performed internally by way of translating an internal optical fiber in the focal plane of the transceiver telescope using miniature motorized translation systems and/or micro-electro-mechanical systems (MEMS). The optical design of the transceiver provides a wide field of view and a pointing and tracking field of regard that is directly proportional to the translation of the optical fiber in the focal plane of the telescope. The apparatus and method can eliminate the need for external gimballing systems and scanning mirrors, and replace the gimballed optical beam steering function with motorized translation systems and/or MEMS that consumes very little power.

Beam steering for optical target identification and tracking without gimbals or scanning mirrors

A MEMS-based optical steering apparatus for free space optical transmitters, receivers, and transceivers is disclosed. The MEMS device comprises actuators linked to an optic fiber, the actuators operable to maneuver the optical fiber in the X-Y plane at the focal point of the transmitter, receiver, or transceiver. The MEMS device may thus be used to replace gimbals for beam steering applications.
