Patent number: 8334797Abstract: A method of performing analog to digital conversation of an analog signal Vin(t), the method including the steps of: utilizing both of the complementary arms of an electro-optic modulator to recover the analog input signal Vin(t), while using only one time-stretch element and one ?-demultiplexer after the electro-optic modulator. The single time-stretch element and one ?-demultiplexer serve to stretch and demultiplex the signals from both of the complementary output arms of the electro-optic modulator thereby improving and simplifying post-processing algorithms used to correct for static distortions and nonlinearities that originate from imperfect photonic hardware. Double-balanced photoreceivers are preferably coupled to outputs of the single ?-demultiplexer. The single time-stretch element is preferably implemented by a chirped fiber grating. Apparatus for carrying out the method is described.Type: GrantFiled: April 20, 2010Date of Patent: December 18, 2012Assignees: HRL Laboratories, LLC, Aerospace Corp.Inventors: Willie W. Ng, George C.

Patent number: 6674220Abstract: An improved, temperature-compensated piezoelectric force motor features greater dynamic range and robustness as compared to previous motor designs. By implementing positive and negative expanding elements, the overall motor length is held constant over temperature. A central stretching member removes the PZT element from the load path of the motor when the motor is relaxed, thereby preventing damage to the element during assembly and deployment. When the piezoelectric element is powered, the central structural member also improves the failure strength of the assembly to further increase the robustness of the motor design. The invention finds applicability in various commercial products including, but not limited to, scientific etalons, nanopositioning systems, custom fiber optic assemblies, and custom CCD detectors.Type: GrantFiled: February 14, 2002Date of Patent: January 6, 2004Assignee: Michigan Aerospace Corp.Inventors: Paul B.

Patent number: 5867071Abstract: A high power RF transmitter that uses high power modulators that perform quadrature amplitude modulation (QAM) on a carrier signal after power amplification that is performed in the RF carrier source. The present invention transposes the locations of the modulators and power amplifier, and thus directly modulates a high power carrier signal. An RF carrier source generates a high power RF carrier signal that is split by a power splitter. A lookup table containing 2.sup.B words by K bits receives transmit data and mapping data and generates K-tuple modulating data. A plurality of phase key modulators are respectively coupled to outputs of the power splitter and to the lookup table and phase key modulate each of the signal components of the carrier signal using the K-tuple modulating data. A power combiner is coupled to outputs of the phase key modulators for outputting a high power QAM constellation from the transmitter.Type: GrantFiled: August 15, 1997Date of Patent: February 2, 1999Assignee: Lockheed Martin Aerospace Corp.Inventor: Frank Chethik

Patent number: 5751769Abstract: An equalizer that mitigates both linear and nonlinear distortions for amplitude phase keyed signals that are processed thereby. Algorithms employed in the equalizer are based on correcting received signals based on symbol transitions between successive symbols. The linear portion of the equalizer is programmable and can use any available algorithm. Programmable linear taps of the equalizer may be programmed in a nonlinear manner by using the lookup tables as amplitude dependent equalizers that are used to process one symbol at a time. In the equalizer, each amplitude level has it's own correction factor by using amplitude dependent coefficients. The equalizer can implement both linear and nonlinear equalization. Equalizer corrections are implemented using predetermined values stored in lookup tables. The equalization corrections are determined in an external computer and are loaded into the lookup tables for each amplitude level of the received signals.Type: GrantFiled: October 22, 1996Date of Patent: May 12, 1998Assignee: Lockheed Martin Aerospace Corp.Inventors: James Pressey, Richard Koralek, Francis J.

Patent number: 5666124Abstract: A high gain Cassegrain reflector antenna system is disclosed for use in a RF signal receiving application. In one embodiment of the invention the antenna is a single parabolic reflector antenna having a plurality of feeds, while in another embodiment the RF signal is received by a number of parabolic reflector antennas. Each received RF signal component is separately amplified to produce corresponding individual amplified signals which are then summed to produce a summation signal. A phase difference between the summation signal and each individual amplified signal is determined, and each individual amplified signal is then phase adjusted until it is in a substantially coherent phase relationship with the summation signal. The phase adjustment compensates for phase displacement errors occurring due to, by example, an effective sector displacement error of a primary reflector of the Cassegrain antenna assembly.Type: GrantFiled: December 14, 1995Date of Patent: September 9, 1997Assignee: Loral Aerospace Corp.Inventors: Frank Chethik, Bryan S.
