    Abstract: An image data set acquired by an optical coherence tomography (OCT) system is corrected for effects due to motion of the sample. A first set of A-scans is acquired within a time short enough to avoid any significant motion of the sample. A second more extensive set of A-scans is acquired over an overlapping region on the sample. Significant sample motion may occur during acquisition of the second set. A-scans from the first set are matched with A-scans from the second set, based on similarity between the longitudinal optical scattering profiles they contain. Such matched pairs of A-scans are likely to correspond to the same region in the sample. Comparison of the OCT scanner coordinates that produced each A-scan in a matching pair, in conjunction with any shift in the longitudinal scattering profiles between the pair of A-scans, reveals the displacement of the sample between acquisition of the first and second A-scans in the pair.

  • Publication number: 20140240675
    Abstract: Methods for improving gaze tracking are presented. These methods eliminate the need for a separate initial calibration step to determine whether the subject is properly centrally fixated during testing. In one embodiment, whether the subject is centrally fixated is determined by identifying inlier and outlier gaze descriptors; the inliers are assumed to be associated with central fixation. This reduces the total time required for testing. These methods also improve the accuracy of gaze tracking during testing without the need for individual subject calibration. Instead, a database of reference eyes is used. The subject's eye can be compared to the reference eyes, and the mapping function for one or more reference matches can be used to estimate the subject's gaze direction. In another embodiment, previous calibration data from the same subject can be used to determine whether the subject is properly centrally fixated and/or the direction of the subject's gaze.

    Abstract: A method and system are presented directed to a light valve projector with a laser-phosphor light converter. The phosphor converter converts excitation light in order to provide light to a light valve projector. The phosphor converter reduces the étendue of laser-phosphor light sources using a light pipe integrator system. The light pipe integrator system includes a light pipe integrator configured to mix the excitation light and reduce the spot size of excitation light entering the system from, e.g., a laser array. The excitation light is imaged onto a phosphor as it exits the light pipe integrator. The phosphor emits fluorescent light, in response to being illuminated by the excitation light, that enters the light pipe integrator. The light pipe integrator reduces the emission angles of the fluorescent light while maintaining the étendue of the fluorescent light. The system and method may include a reflective polarizer to polarize the fluorescent light.

The step difference estimation unit estimates step difference of a processing layer. The assist pattern generation unit adds an assist pattern having different sensitivity to spherical aberration in an exposure process to a mask pattern based on the step difference of the processing layer. The spherical aberration conversion unit converts the step difference of the processing layer into the spherical aberration.

  • Publication number: 20140240684
    Abstract: An exposure apparatus having a projection system with a final element projects exposure light to an upper surface of a substrate through liquid between the final element and the substrate upper surface. A liquid confinement member has a recovery outlet via which the liquid is removed along with gas, the recovery outlet being arranged such that the substrate upper surface faces the recovery outlet, the recovery outlet surrounding a path of the exposure light and the liquid confinement member confining the liquid to an area that is smaller than an area of the substrate upper surface by removing the liquid from a gap between the confinement member and the substrate upper surface. A first support member supports the projection system, and a second support member supports the liquid confinement member. An anti-vibration system limits vibrations from being transmitted from the second support member to the projection system.

  • Publication number: 20140240685
    Abstract: An exposure apparatus irradiates a substrate with light via a projection system and liquid, and includes a stage that moves below the projection system, and a light-receiving element having a light-receiving surface. An optical member provided on the stage has a first surface contacting the liquid when moved to face the projection system, and a second surface contacting a gas and transmitting light having come from the projection system via the liquid and the first surface. The optical member is configured such that at least a large-angle ray of the light, which has an angle with an optical axis of the projection system sufficiently large to undergo total reflection at an end surface of the projection system when the liquid is absent, travels from the projection system to the second surface without passing through gas. The second surface transmits the large-angle ray, which is received by the light-receiving surface.

  • Publication number: 20140240688
    Abstract: A synchronization method for at least two sensors, which enables synchronized collection of a sensor value of a slave sensor in relation to a predetermined intended value of a master sensor. Time-dependent measured values of the master sensor are used to determine open parameters of a prediction model, on the basis of which a time associated with a master sensor intended value to be predetermined is extrapolated. When this time is reached, a synchronization signal triggering the recording of a slave sensor value, in particular the recording of a measured value, is transmitted to the at least one slave sensor. Master sensor intended value and slave sensor value are provided as connected value tuple. As a result of continuous collection of measured values by the master sensor, it is possible to form updated extrapolation rules continuously. Predetermined intended values of the master sensor can have, in particular, an equidistant spacing.

    Abstract: The present disclosure describes methods and systems, including computer-implemented methods, computer-readable media, and computer systems, for measuring range to an object (e.g., range finding) by reflection of laser radiation. One computer-implemented method includes the following operations executed on a mobile computing device (MCD): targeting an object with the MCD display operating as a viewfinder, receiving a request to trigger a laser range finding operation, initiating triggering of an emitter on a laser range finding attachment (LRFA) coupled to the MCD, receiving range finding data from the LRFA, processing the range finding data, and initiating display of data associated with the object, the data corresponding to the processed range finding data.

  • Publication number: 20140240690
    Abstract: A method of determining extrinsic calibration parameters for at least one sensor (102, 104, 106) mounted on transportable apparatus (100). The method includes receiving (202) data representing pose history of the transportable apparatus and receiving (202) sensor data from at least one sensor mounted on transportable apparatus. The method generates (204) at least one point cloud data using the sensor data received from the at least one sensor, each point in a said point cloud having a point covariance derived from the pose history data. The method then maximises (206) a value of a quality function for the at least one point cloud, and uses (208) the maximised quality function to determine extrinsic calibration parameters for the at least one sensor.

  • Publication number: 20140240692
    Abstract: A time-of-flight (TOF) sensor pixel is provided that performs in-pixel subtraction. The TOF sensor pixel includes a photodetector, a capacitor, and circuitry. The photodetector detects light pulses emitted at a clock frequency, after a time of flight, to provide a photocurrent. The capacitor integrates the photocurrent over an integration period, while the circuitry reverses a flow direction of the photocurrent through the capacitor at twice the clock frequency. At the end of the integration period, the capacitor provides a differential photocharge, corresponding to a capacitor voltage. The capacitor voltage is related to the time of flight of the light pulses and may be used to determine a distance to a target.
