Abstract: Optical imaging systems and methods providing having variable lateral zoom. In one example, an optical imaging system with variable lateral zoom includes primary optics configured to receive and direct incident electromagnetic radiation from a viewed scene onto a focal plane to form a substantially planar intermediate image at the focal plane, the intermediate image having substantially uniform lateral magnification, an eyepiece optically coupled to the primary optics and configured to reimage the intermediate image onto an image plane to produce an output image having variable lateral magnification, and a photo-sensitive detector positioned at the image plane.

Abstract: Monostatic optical transceivers, systems, and methods of operating the same include a single aperture, a transmitter that provides a modulated and polarized optical transmit beam, a receiver that receives a modulated and polarized optical receive beam at an optical resonator included therein and processes the received optical receive beam to determine information from the received optical receive beam, a polarizing beam splitter that reflects the optical transmit beam, a polarization rotator that rotates the polarization of the reflected optical transmit beam by a fixed number of degrees in a transmit direction in a coordinate system of the monostatic transceiver, and a waveplate that modifies the polarization of the rotated optical transmit beam.

Abstract: Free space optical systems and methods of controlling the same for reducing signal fading of encoded optical beams transmitted in a communication channel are provided. Adjacent pairs of a plurality of apertures are separated by a distance being at least greater than the coherence width of the propagation medium of the communication channel. Due to averaging of the beams, variation in power at an optical receiver is reduced. By using an optical resonator in the optical receiver, the beams are converted into an intensity modulation on a non-interfering basis, thereby permitting recovery and decoding of the signal.

Abstract: Method and apparatus to maintain a resonant condition of an optical cavity such that the optical path length through the optical cavity is independent or minimally dependent on the angle of incidence of a received optical signal are disclosed. A material within the optical cavity has an index of refraction that varies as a function of an angle of propagation of light within the material, thereby achieving the independence of the optical path length and the angle of incidence. The resonant condition is maintained over a range of angles of incidence of the received optical signal.

Abstract: An optical receiver including an optical resonator and a steering mechanism coupled to the at least one optical resonator is disclosed. The optical resonator is configured to receive a phase modulated input optical signal and to produce an intensity modulated output optical signal. An intensity modulation of the output optical signal is representative of the phase modulation of the input optical signal. The optical receiver further comprises an optical-electrical converter that detects the intensity modulated output optical signal and converts the intensity modulated output optical signal to an electrical signal, and signal processor that receives the electrical signal, performs symmetric phase change measurements based on the electrical signal, and provides a control signal to actuate the steering mechanism to steer the optical resonator to maintain normal incidence of the phase modulated input optical signal on a surface of at least one optical resonator.

Abstract: A system includes a table and a material detection system. The material detection system includes a transmit chain configured to generate first radio frequency (RF) signals and a transmit probe configured to transmit the first RF signals towards an item through open space. The material detection system also includes a receive probe configured to receive second RF signals from the item through open space, where the second RF signals have one or more characteristics indicative of one or more materials within the item. The material detection system further includes a receive chain configured to process the second RF signals and at least one processing device configured to identify the one or more materials within the item using nuclear quadrupole resonance (NQR) spectrometry based on the processed second RF signals. The transmit and receive probes are positioned in an upper portion of the table.
