System And Method For Effecting High-Power Beam Control With Outgoing Wavefront Correction Utilizing Holographic Sampling At Primary Mirror, Phase Conjugation, And Adaptive Optics In Low Power Beam Path
US Patent:
6849841, Feb 1, 2005
Filed:
Sep 28, 2001
Appl. No.:
09/965929
Inventors:
Robert W. Byren - Hermosa Beach CA, US
Alvin F. Trafton - Manhattan Beach CA, US
Alvin F. Trafton - Manhattan Beach CA, US
Assignee:
Raytheon Company - Waltham MA
International Classification:
G01J 120
US Classification:
2502019, 2502011
Abstract:
A beam control system and method. In an illustrative embodiment, the inventive system () provides a first beam of electromagnetic energy (); samples the first beam () and provides a second beam () in response thereto; detects aberrations in the second beam (); and corrects aberrations in the first beam () in response to the detected aberrations. In a specific implementation, the invention () includes a beam director telescope () having a primary mirror () on which a holographic optical element () is disposed. The holographic optical element () samples the output high-power beam and provides a sampled beam to a wavefront sensor (). The wavefront sensor () provides signals to an adaptive optics processor (). The adaptive optics processor () analyzes the sampled wavefront, detects aberrations therein and provides a correction signal to an optical phased array ().

Abstract:
A beam control system and method which utilizes the wavefront reversal property of nonlinear optical phase conjugation to permit incorporation of a liquid crystal OPA within the low power legs of the beam control system, thereby affording the advantages of the OPA without the power limitations thereof. The invention is adapted for use with a beacon for illuminating a target with a first beam of electromagnetic energy. The system includes a telescope () for receiving a target return comprising a reflection of the first beam from the target. An optical phased array () is included for correcting for aberrations in the wavefront of the target return. A mechanism is included for ascertaining the correction applied by the optical phased array to the target return. The mechanism applies the correction to a third beam which ultimately is the output beam. In the illustrative embodiment, the first beam of electromagnetic energy is optical energy and the mechanism includes a first phase conjugate mirror () adapted to conjugate electromagnetic energy output by the third mechanism and a second phase conjugate mirror () adapted to conjugate the output of the first phase conjugate mirror. The fourth mechanism further includes an amplifier () for boosting the signal output by the second phase conjugate mirror () to provide the output beam.
