摘要： Systems, methods, and non-transitory computer readable media including instructions for performing operations for continuous authentication based on facial skin micromovements is disclosed. The operations may include receiving during an ongoing electronic transaction, first signals representing coherent light reflections associated with first facial skin micromovements during a first time period and second signals representing coherent light reflections associated with second facial skin micromovements during a second time period. The operations may also include determining, using the first and second signals, that a specific individual is associated with the first and second facial skin micromovements. The operations may also include receiving during the ongoing electronic transaction third signals representing coherent light reflections associated with third facial skin micromovements. The operations may further include determining, using the third signals, that the third facial skin micromovements are not associated with the specific individual, and initiating an action based on the determination.

摘要： Methods and systems for combined Spectroscopic Reflectometry (SR) and Pattern Recognition (PR) based image measurements of semiconductor structures at high throughput are presented herein. Measurements of large pitch targets and thick targets through die with improved fringe contrast, resolution, and spectral fidelity are enabled. A PR based imaging subsystem generates illumination light ranging from visible to short infrared wavelengths. A SR subsystem generates illumination light ranging from the deep ultraviolet to short infrared wavelengths. The SR subsystem includes low Numerical Aperture (NA) optics to realize a relatively large size illumination and collection spot. Both the SR subsystem and the PR based imaging subsystem share the same objective and resolve signals from different depths of a structure under measurement. In some embodiments, a combined machine learning based measurement model estimates values of one or more parameters of interest based on both SR and PR image signals.

摘要： The present disclosure is related to an optical encoder which is configured to provide precise coding reference data by feature recognition technology. To apply the present disclosure, it is not necessary to provide particular dense patterns on a working surface. The precise coding reference data can be generated by detecting surface features of the working surface.

摘要： A latent print extraction apparatus I comprising: an input operable to receive an 5 image of light reflected from a curved surface: a comparison unit 6 operable to compare a shape of the reflected light in the image to an expected shape of light reflected from a flat surface and thereby determine an estimated curvature for the curved surface: and a correction unit I I operable to correct curvature distortions of an image of a latent print on the curved surface based on the estimated curvature. The latent print extraction 10 apparatus I means calculation of a value for the curvature of the curved surface can be done remotely, without the need to physically measure the surface. This saves time, and avoids accidentally or otherwise contacting any latent prints when measuring the curvature of the surface.

摘要： A detection system for a vehicle includes an imaging device configured to capture an image of an interior surface of the vehicle. An illumination assembly includes an array of laser diodes each configured to project an illumination, each laser diode is configured as at least one of a single mode laser or a vertical-cavity surface-emitting laser (“VCSEL”). An optical element is proximate to the array of laser diodes and includes a collimation element for guiding the illumination to form at least one light spot. A processor is in communication with the imaging device and the illumination assembly. The processor is configured to communicate a signal to operate the array of laser diodes and process the image of the interior surface to detect at least one of a change in a location or a speckle content of the at least one spot.
