Abstract: Embodiments of the present invention relate to methods and apparatus for detecting atmospheric nitric oxide (NO) at signal levels capable of distinguishing the NO isotopologues. More particularly, embodiments of the present invention relate to methods and apparatus for a single photon laser induced fluorescence (LIF) sensor that pumps a vibronic transition near 215 nm and observes the resulting red shifted fluorescence from about 255 to about 267 nm. Embodiments of the present system uses a NO-LIF measurement fiber-amplified laser apparatus capable of: generating laser linewidth that is sufficiently narrow to resolve the Doppler broadened NO spectrum at room temperature and thereby achieve high signal levels and distinguish the NO isotopologues; generating laser repetition rate sufficient to enable single-photon counting of the fluorescence signal; and having size, weight and environmental robustness allowing for integration onto airborne platforms.

Abstract: This disclosure relates to an OCT apparatus configured to generate to electromagnetic (e.g., optical) signals having two different polarization states. Two or more silicon optical amplifiers (SOAs) can be configured to maintain a respective polarization state in an optical input signal provided from a light source (e.g., a broadband light source). The different polarization states can be combined by an optical combiner (e.g., a polarization maintaining fiber coupler) and provided to drive a reference arm and a sample arm implemented in an OCT system.

According to one aspect, an augmented reality computer system includes processing circuitry configured to access an image of the real world, wherein the image includes a real world object, and evaluate the image using a neural network to determine a plurality of augmented reality estimands which are indicative of a pose of the real world object and which are useable to generate augmented content regarding the real world object. Other methods and systems are disclosed including additional aspects directed towards training and using neural networks.

Abstract: Systems, methods, and other embodiments associated with gated optical coherence tomography (OCT) are described. One example method includes generating an image control signal to control an OCT apparatus to acquire an image of an embryonic heart at a specified point in time during a cardiac cycle of the embryonic heart. The method may also include controlling the OCT apparatus to acquire the image based on the image control signal. In different examples, the image may be acquired in vivo or from an excised heart that is paced. The OCT apparatus and the embryonic heart may be housed in an environmental chamber having a set of controllable environmental factors. Therefore, the method may include detecting and controlling the set of controllable environmental factors.

Abstract: A system and related methods for automatic or semi-automatic segmentation and quantification of blood vessel structure and physiology, including segmentation and quantification of lumen, guide wire, vessel wall, calcified plaques, fibrous caps, macrophages, metallic and bioresorbable stents are described, and including visualization of results. Calcified plaque segmentation can be used to estimate the distribution of superficial calcification and inform strategies stenting. Volumetric segmentation and quantification of fibrous caps can provide more comprehensive information of the mechanisms behind plaque rupture. Quantification of macrophages can aid diagnosis and prediction of unstable plaque and associated acute coronary events. Automated detection and quantification of metallic and bioresorbable stents can greatly reduce the analysis time and facilitate timely decision making for intervention procedures.

Abstract: Techniques for tracking a pose of a textured target in an augmented reality environment are described herein. The techniques may include processing an initial image representing the textured target to generate feature relation information describing associations between features on different image layers of the initial image. The feature relation information may be used to locate features in different image layers of a subsequent image. Upon locating features in a highest resolution image of the subsequent image, the pose of the textured target may be determined for the subsequent image.

Abstract: Architectures and techniques for augmenting content on an electronic device are described herein. In particular implementations, a user may use a portable device (e.g., a smart phone, tablet computer, etc.) to capture images of an environment, such as a room, outdoors, and so on. As the images of the environment are captured, the portable device may send information to a remote device (e.g., server) to determine whether augmented reality content is associated with a textured target in the environment (e.g., a surface or portion of a surface). When such a textured target is identified, the augmented reality content may be sent to the portable device. The augmented reality content may be displayed in an overlaid manner on the portable device as real-time images are displayed.

An imaging component is operative to obtain an image of the eye tissue. A first image of the tissue can be obtained prior to the introduction of the stress and a second image of the tissue can be obtained after the introduction of the stress. An image analysis component compares the first image and the second image as to determine at least one biomechanical property of the tissue.

Abstract: Spatial information, such as concentration and displacement, about a specific molecular contrast agent, may be determined by stimulating a sample containing the agent, thereby altering an optical property of the agent.

The acquired images are used to profile the molecular contrast agent concentration distribution of the sample.
