Patents by Inventor Lionel D. Liebman

Lionel D. Liebman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8049869
    Abstract: The present invention includes a multifaceted imaging semi-active laser system (“I-SALS”). In one aspect, the I-SALS closes on a laser designation of a target until it starts imaging the target, whereupon the I-SALS then homes on the target from the image. Some embodiments employ a slightly defocused designation. Other embodiments use existential jitter in the designation and other embodiments intentionally induce a jitter in the designation called dither. One particular embodiments provides a dual field-of-view optics package that has no moving parts.

  • Patent number: 7705290
    Abstract: A multi-beam LADAR apparatus and a method for use in a multi-beam LADAR system are disclosed. The apparatus includes a plurality of mission specific optics; a gimbal in which the mission specific optics are mounted; an off-gimbal laser; and a multi-fiber relay optically linking the laser output to the mission specific optics. The method includes gimbaling a plurality of mission specific optics; generating a laser signal off the gimbal; and optically relaying the laser signal to the mission specific optics through a plurality of discreet channels.

  • Patent number: 7649616
    Abstract: A laser radar system and a method for use in a laser radar system are disclosed. More particularly, the laser radar system includes a fiber laser capable of generating a laser signal; a first optical path through which the generated laser signal may be transmitted; a second optical path through which a reflection of the transmitted laser signal may be received; and a detector capable of detecting the received reflection. The method includes generating a laser signal from a fiber laser; transmitting the laser signal; receiving a reflection of the transmitted laser signal; and detecting the reflection.

  • Patent number: 7375804
    Abstract: A LADAR apparatus and a method for use in receiving a LADAR signal are disclosed. The apparatus includes an optical pickup capable of picking up a plurality of optical signals; a timing synchronization reference; a time domain multiplexer capable of multiplexing the optical signals into a multiplexed optical signal relative to the timing synchronization reference; and an optical detector capable of detecting the multiplexed optical signal. The method include time domain multiplexing a plurality of LADAR signals into multiplexed LADAR signal; detecting the multiplexed LADAR signal; and demultiplexing the detected LADAR signal.
