摘要： Described are a method and apparatus for high-speed phase shifting of an optical beam. A transparent plate having regions of different optical thickness is illuminated by an optical beam along a path of incidence that extends through the regions. The transparent plate can be moved or the optical beam can be steered to generate the path of incidence. The optical beam exiting the transparent plate has an instantaneous phase value according to the region in which the optical beam is incident. Advantageously, the phase values are repeatable and stable regardless of the location of incidence of the optical beam within the respective regions, and phase changes at high modulation rates are possible. The method and apparatus can be used to modulate a phase difference of a pair of coherent optical beams such as in an interferometric fringe projection system.

摘要： A diode laser [100, 200] for providing a high-energy coherent light beam [124, 224] suitably includes an array of laser diodes [101, 201] each producing a laser beamlet [120, 220]. The beamlets are provided to a spatial light modulator (SLM) [102, 202] with an array of pixels, each pixel corresponding to a portion of the light beam. The phase variation across the light beam wavefront is monitored at a detector [106, 206], and a feedback signal [107, 207] indicative of the phase variation is provided to control electronics [108, 208]. The control electronics process the feedback signal to modulate a local index of refraction within one or more pixels of the SLM to reduce the variation in phase across the beam wavefront. Because phase variations across the beam wavefront are reduced, relatively large diode arrays can be formulated, thereby resulting in relatively high powered diode lasers.

摘要： A system of beam steering using electrical operation. A first system provides a grating (104) and a liquid crystal material (128). When the liquid crystal is unenergized, there is a mismatch between the liquid crystal and the grating, causing the grating to diffract the light (130) in a specified direction. The liquid crystal is energized to match its index of refraction to the grating. Then, the light is not diffracted by the grating, and hence travels in a different direction than it would when the liquid crystal was not energized. Another, finer system, forms electrically generated gratings using a liquid crystal material.

摘要： The present invention includes time delay devices and time delay systems. The invention also includes machines and instruments using those aspects of the invention. The invention may also be used to upgrade, repair, or retrofit existing machines or instruments, using methods and components known in the art. The present invention comprises a true time device that falls into the free-space category but uses a multiple-pass optical cell with a beam splitter (28) and refocusing mirrors (13, 14, 24, 25) that have the advantage of avoiding beam spreading problems. The approach differs from previous free-space approaches in that it uses only one optical switch or spatial light modulator (12) instead of one or more switches for each bit. In one approach, a microwave signal for each antenna element may be modulated onto an optical beam. After the individual optical beams are delayed by the desired amount of time through the system, the signal may then be down-converted to microwave signals for further processing. This process may be used in either the transmit or the receive mode of a phased array radar.

摘要： An optical phased array (OPA) receiver selectively detects, measures and differentiates between the amplitudes and directions of signals received from different directions. Because the OPA changes the direction that it looks toward electronically and without the use of any mechanical movements, the OPA is fast, has an enhanced sensitivity, and can be used in a wide variety applications, such as lens-free imaging systems. The OPA is adapted to dynamically control the array of optical elements and focus on the area of interest. The OPA achieves a higher numerical aperture compared to imaging systems that use conventional lens, thereby effectively maintaining a relatively large field of view and collection area concurrently. The OPA may be readily scaled by increasing its array size. Furthermore, because the OPA is relatively flat, it is ideally suited for small form factor applications such as cell phones and tablets.
