An integrated optical fiber gyroscope chip based on surface Plasmon Polariton waveguide is an integrated optical fiber gyroscope chip in which optical signal is transmitted through the surface Plasmon Polariton waveguide and the polymer optical waveguide which are connected with each other, and it is used in the optical fiber gyroscope field. From the input end to the output end, the optical fiber gyroscope chip sequentially has: an input waveguide (1) and the third output waveguide (7), a directional coupler (2), a symmetrical triple waveguide splitter (3), the first output waveguide (61) and the second output waveguide (62), wherein the input waveguide (1), the first output waveguide (61), the second output waveguide (62) and the third output waveguide (7) are polymer optical waveguides, but the directional coupler (2) and the symmetrical triple waveguide splitter (3) are made from the surface Plasmon Polariton waveguide. The chip utilizes the transmission characteristics of the surface Plasmon Polariton waveguide to realize the single polarization of long-distance transmission of the optical signal, and directly modulates the surface Plasmon Polariton waveguide core layer, and removes influence of the leakage light to the precision of the fiber gyroscope through the specific structure.
摘要:
A family of one-dimensional image signatures is obtained to represent each one of a sequence of images in a number of translational and rotational orientations. By calculating these image signatures as images are captured, a new current view can be quickly compared to historical views in a manner that is less dependent on the relative orientation of a target and search image. These and other techniques may be employed in a three-dimensional reconstruction process to generate a list of candidate images from among which full three-dimensional registration may be performed to test for an adequate three-dimensional match. In another aspect this approach may be supplemented with a Fourier-based approach that is selectively applied to a subset of the historical images. By alternating between spatial signatures for one set of historical views and spatial frequency signatures for another set of historical views, a pattern matching system may be implemented that more rapidly reattaches to a three-dimensional model in a variety of practical applications.

摘要:
One or more facial recognition categories are assigned to a face region detected in an input image (24). Each of the facial recognition categories is associated with a respective set of one or more different feature extraction modules (66) and a respective set of one or more different facial recognition matching modules (76). For each of the facial recognition categories assigned to the face region, the input image (24) is processed with each of the feature extraction modules (66) associated with the facial recognition category to produce a respective facial region descriptor vector of facial region descriptor values characterizing the face region. A recognition result (96) between the face region and a reference face image (28) is determined based on application of the one or more facial recognition matching modules (76) associated with the facial recognition categories assigned to the face region to the facial region descriptor vectors produced for the face region detected in the input image (24).

摘要:
Interest regions are detected in respective images (18) having face regions labeled with respective facial part labels. For each of the detected interest regions, a respective facial region descriptor vector of facial region descriptor values characterizing the detected interest region is determined. Ones of the facial part labels are assigned to respective ones of the facial region descriptor vectors. For each of the facial part labels, a respective facial part detector (20) that detects facial region descriptor vectors corresponding to the facial part label is built. The facial part detectors (20) are associated with rules (30) that qualify segmentation results of the facial part detectors (20) based on spatial relations between interest regions detected in images and the respective face part labels assigned to the facial part detectors (20). Faces in images are detected and recognized based on application of the facial part detectors (20) to images.
摘要:
Key technologies have been developed in realizing single longitudinal mode CW operation with a regular standing-wave cavity for intracavity frequency doubling and intracavity frequency conversions, so as to produce all solid-state, true cw devices with operation over wide spectral ranges including green, blue and UV. In one method laser arrangement, a beam expander (23 or 41) is applied to render a large mode waist and an improved beam divergence so as to greatly reduce the insertion losses for intracavity optical elements (17, 18 or 44). In another method laser arrangement, when spatial hole burning interference effect is minimized by using a pump head (12) with a thin gain zone (2) in contact with an end cavity mirror, then a low resolving-power spectral filter with low loss can be utilized. In addition, several novel optical multipass constructions, typically by use of total-internal-reflection, have also been devised for pumping laser chips, laser rods, laser slabs, and for the use of multipass optical amplifier and pumping fiber lasers.
