摘要： The disclosure describes the use of image sensors in a variety of different imaging applications. In some implementations, the pixels of an image sensor may be configured (e.g., programmed) with one or more analog filters to sense a variety of things, including, for example: average intensity and color (like a standard camera), 3D depth (like a time of flight or structured light camera), changes and/or motion in an image (like an event based camera), spectral reflectance (like a spectroscopy camera), and many other features of an imaged scene or object. In alternative implementations, digital filtering may be applied to the output of an image sensor to realize one of these applications.

摘要： A distance measuring method and an electronic laser distance measuring module, for determining a distance to a target object, wherein the transmitted signal is emitted with selected polarization states by a transmitting unit of the laser distance measuring module. The transmitted signal is emitted and the received signal is acquired such that a polarization identifier of the polarization state of the transmitted signal adheres to the received signal and an evaluation of the received signal is derived based on the polarization identifier, to take into consideration multiple reflections during the processing of the received signal to determine the distance.

摘要： Apparatus and associated methods relate to determining, based on a detected portion of a projected pulse of quasi-optical energy backscattered by water particles within a divergent projection volume of a cloud atmosphere, properties of the backscattering water particles. The pulse of quasi-optical energy is projected into the divergent projection volume of the cloud atmosphere. The divergent projection volume is defined by an axis of projection and an angle of projection about the axis of projection. The portion of the projected pulse of optical energy backscattered by water particles within the divergent projection volume of the cloud atmosphere is received and detected. Various properties of the backscattering water particles, which can be determined from the detected portion of the projected pulse backscattered by water particles can include particle density and/or particle size.

摘要： Methods, systems, and apparatuses are provided for estimating a location on an object in a three-dimensional scene. Multiple radiation patterns are produced by spatially modulating each of multiple first radiations with a distinct combination of one or more modulating structures, each first radiation having at least one of a distinct radiation path, a distinct source, a distinct source spectrum, or a distinct source polarization with respect to the other first radiations. The location on the object is illuminated with a portion of each of two or more of the radiation patterns, the location producing multiple object radiations, each object radiation produced in response to one of the multiple radiation patterns. Multiple measured values are produced by detecting the object radiations from the location on the object due to each pattern separately using one or more detector elements. The location on the object is estimated based on the multiple measured values.

摘要： Apparatus and associated methods relate to sampling a large volume of a cloud atmosphere so as to obtain a large signal response from even a sparse distribution of water droplets in the cloud atmosphere. Such a volume can be probed by projecting an uncollimated optical beam into the cloud atmosphere and sampling the signal backscattered from the water droplets located within the probed volume. The uncollimated optical beam can be generated by projecting a diverging pulse of light energy from a polished end of a first optical fiber. A second optical fiber can be used to receive the optical signal backscattered from the cloud atmosphere. The second optical fiber can also have substantially the same field of view as the first optical fiber, so as to receive signals from a volume of the cloud atmosphere that is substantially commensurate with the probed volume.

摘要： Apparatus and associated methods relate to determining sizes of water particles in a cloud atmosphere based on a detected portion of signals generated from a single monochromatic source and backscattered by water particles in a cloud atmosphere. A backscatter coefficient and an optical extinction coefficient are calculated, based on the detected portion of signals generated from the monochromatic source and backscattered by water particles in the cloud atmosphere. A LIDAR ratio—a ratio of the optical extinction coefficient to the backscatter coefficient, is calculated. Sizes of water particles in the cloud atmosphere are estimated based on the LIDAR ratio. An output signal indicative of the estimated sizes of water particles in the cloud atmosphere is generated. Estimating sizes of water particles using signals from a single monochromatic source advantageously can alert a pilot of an aircraft of cloud conditions, without requiring multi-chromatic sources.

摘要： A device for emission of polarized light and its detection including a light emitter configured to generate an outgoing light beam directed along an optical emission axis, a light receiver configured to detect an incoming light beam directed along an optical detection axis, and a polarization unit positioned in the optical emission axis and optical detection axis and configured to polarize the outgoing light beam and the incoming light beam. To allow a compact assembly, the device, by reducing the number of its constituent parts and by providing a good detection reliability of the device, the optical emission axis and the optical detection axis are angled with respect to one another such that they include an intersection point and the polarization unit includes a polarizer configured to deflect light from at least one of the incoming light beam towards the optical detection axis and the outgoing light beam away from the optical emission axis, the deflected light being defined by a polarization state produced by the polarizer.
