Abstract: The device is based on a cross-correlator which measures the signal between a pair of oppositely chirped laser pulses. Two laser pulses, one with a positive chirp and one with a negative chirp, are mixed on a beamsplitter. The two resulting beams pass through a reference or a sample arm and are subsequently mixed on a non-lmear crystal. The signal from the interferometer is the sum frequency generation produced in that crystal. The reference arm contains a moveable delay which is used to change the relative timing of the two beams in the interferometer. The sum frequency generation in the narrow band of frequencies is the signal from the device and is measured as a function of the delay. Alternatively, a pure dispersive phase shift could be used in place of the two laser pulses.

Abstract: Phase-conjugate optical coherence tomography (PC-OCT) methods and apparatus. PC-OCT may be employed as a three-dimensional imaging technique of interest for biomedical and other imaging applications. It shares much of the source and detection convenience of conventional OCT employing classical light sources, which is in clinical use in ophthalmology and is being developed for a variety of endoscopic optical biopsy instruments. PC-OCT offers a two-fold improvement in axial resolution and immunity to group velocity dispersion, when compared with conventional OCT, that is available from quantum optical coherence tomography (Q-OCT). PC-OCT does this without Q-OCT' s need for a non- classical light source and the attendant requirement of photon-coincidence counting detection. Thus, in comparison with Q-OCT, PC-OCT is capable of producing images in measurement times similar to those of conventional OCT.

Abstract: A device for detecting an object includes a beam splitter (BS1) which splits a beam of light from a source between a first path (U) and a second path (D). The first path (U) includes a first prism (TIR U ) arranged to reflect light from the beam splitter (B S1) by total internal reflection at a sensing surface of the first prism (TIR U ). The total internal reflection creates an evanescent wave at the sensing surface. The second path (D) includes a corresponding second prism (TIR D ). A second beam splitter (BS2) splits light from both the first path (U) and the second path (D) between two detectors (D b , D d ). The first and second paths are configured such that light from the first path (U) and light from the second path (D) interfere constructively in the direction of one of the detectors (D b ) and destructively in the direction of the other detector (D d ) when no object is present so that no light is received by the detector (D d ). When an object nears the sensing surface of the first prism (TIR U ) in the first path (U), the object scatters the evanescent wave and allows a small fraction of photons to tunnel out of the first prism (TIR U ). This disturbs the total destructive interference at the dark detector (D d ), which therefore detects photons with a non-zero probability. The detection of a photon at this detector (D d ) indicates the presence of an object in the proximity of the sensing surface of the first prism (TIR U ). When single photons are made to pass through the device one at a time, the object can be detected without the photon touching it and being scattered or absorbed.

Abstract: Coherent spectroscopic methods are described, to measure the total phase difference during an extended interrogation interval between the signal delivered by a local oscillator (10) and that given by a quantum system (QS). According to one or more embodiments, the method may comprise reading out at the end of successive interrogation sub-intervals (Ti) intermediate error signals corresponding to the approximate phase difference (φ) between the phase of the LO signal and that of the quantum system, using coherence preserving measurements; shifting at the end of each interrogation sub-intervals (Ti) the phase of the local oscillator signal, by a known correction value ( φ (i) FB ) so as to avoid that the phase difference approaches the limit of the inversion region; reading out a final phase difference (φf) between the phase of the prestabilized oscillator signal and that of the quantum system using a precise measurement with no restriction on the destruction; reconstructing a total phase difference over the extended interrogation interval, as the sum of the final phase difference (φf) and the opposite of all the applied phase corrections figure (I).

Abstract: In one embodiment, an apparatus comprises an optical system with multiple detectors and a processor. The optical system is configured to produce images of an optical source in a first dimension and a second dimension substantially orthogonal to the first dimension at each detector at a given time. Each image from the images is based on an interference of an emission from the optical source in a first direction and an emission from the optical source in a second direction different from the first direction. The processor is configured to calculate a position in a third dimension based on the images. The third dimension is substantially orthogonal to the first dimension and the second dimension.

Abstract: Incoming data from, for example, an array of detectors, may be received. A dynamical system may be initialized corresponding to a modality of the incoming data so that a measurement probe based on the initialized dynamical system may be generated. Such a measurement probe may be injected into a quantum mechanical system so that it may be determined whether the injection of the measurement probe into the quantum mechanical system results in a collapse of the quantum mechanical system. Thereafter, it may be determined that a signal is present within the incoming data if the quantum mechanical system collapses. Related methods, apparatuses, systems, and computer-program products are also described.
