摘要： Techniques are disclosed for magnification compensation and/or beam steering in optical systems. An optical system may include a lens system to receive first radiation associated with an object and direct second radiation associated with an image of the object toward an image plane. The lens system may include a set of lenses, and an actuator system to selectively adjust the set of lenses to adjust a magnification associated with the image symmetrically along a first and a second direction. The lens system may also include a beam steering lens to direct the first radiation to provide the second radiation. In some examples, the lens system may also include a second set of lenses, where the actuator system may also selectively adjust the second set of lenses to adjust the magnification along the first or the second direction. Related methods are also disclosed.

摘要： A linearized electro-optic modulator includes a substrate comprising a first Mach Zehnder interferometer comprising a first and second optical waveguide and a second Mach Zehnder interferometer comprising a first and a second optical waveguide. A signal electrode is positioned on the substrate to receive a modulation signal. First and second ground electrodes are positioned on the substrate and are electrically connected to ground potential. The signal electrode and the first and second ground electrodes are positioned so that an electric field generated by the signal electrode modulates both the first and second Mach Zehnder interferometers to generate a first and a second linearized modulated optical signal.

摘要： A photonically-sampled electronically-quantized analog-to-digital converter generates an optical signal comprising a series of optical pulses. The optical signal is split into a first and a second optical path. The split optical signal is detected in the first path and then the detected optical signal is converted to a reference digital signal. The split optical signal in the second path is modulated with an input RF signal and a plurality of demultiplexed RF-modulated optically-sampled signals is generated from the modulated optical signal. The plurality of demultiplexed RF-modulated optically-sampled signals is then pulse broadened, detected, and converted to a plurality of sampled-RF digital signals. The reference digital signal and the plurality of sampled-RF digital signals are digital signal processed to generate a digital representation of the input RF signal.

摘要： A same-aperture any-frequency simultaneously transmit and receive (STAR) system includes a signal connector having a first port electrically coupled to an antenna, a second port electrically coupled to a transmit signal path, and a third port electrically coupled to receive signal path. The signal connector passes a transmit signal in the transmit signal path to the antenna and a receive signal in the receive signal path. A signal isolator is positioned in the transmit signal path to remove a residual portion of the receive signal from transmit signal path. An output of the signal isolator provides a portion of the transmit signal with the residual portion of the receive signal removed. A signal differencing device having a first input electrically coupled to the output of the signal isolator and a second input electrically coupled to the third port of the signal connector subtracts a portion of the transmit signal in the receive signal path thereby providing a more accurate receive signal.

摘要： A multiple-input multiple output transmit and receive system includes a first antenna that transmits a first signal at a channel frequency that propagates in a first path and that simultaneously receives a pilot signal at the channel frequency with the transmitting the first signal at the channel frequency, where the pilot signal propagates in a second path. A single-channel duplex transmit-receive system is coupled to an output of the first antenna. A processor is coupled to an output of the single-channel duplex transmit-receive system and configured to determine channel state information of the first path at the channel frequency using the received pilot signal.

摘要： An electromagnetic field optimization apparatus providing a means of more independently modifying the field in either the reactive near-field region or the far-field region while having significantly less modification to the other field. This means that a design to affect the real component of the impedance that affects the radiation in the far-field region does not affect, or minimally affects, the reactive component of the impedance that affects the field in the reactive near-field region.

摘要： A simultaneous transmit and receive (STAR) system includes a first bidirectional signal port coupled to an antenna, a second port coupled to a transmit signal path, and a third port coupled to receive signal path. A first switch is electrically connected between the first port and the second port, where a transmit signal propagating in the transmit signal path passes through the first switch when closed and then through the first bidirectional signal port to the antenna where the transmit signal is radiated by the antenna. A second switch is connected between the first port and the third port, where a receive signal is received by the antenna and passes through the bidirectional signal port and then through the second switch when closed to the receive signal path. A controller is electrically connected to a control input of each of the first and second switches.
