摘要： A LIDAR optical remote sensing system and method is disclosed. The system and method analyzes the falling edge profile of a return LIDAR signal that may be indicative of an object or an aerosol cloud, which is generally more diffuse. Use of the falling edge profile permits burnthrough to an object that may be obscured by the aerosol cloud. The profile is compared against at least one threshold that may correspond, in various embodiments, to a negative slope of the falling edge, an integrated power under the falling edge, or a range estimate error for varying transmitted power values, varying transmitted pulse lengths and/or varying receiver detector field of view values.

摘要： A head for directing radiated energy from a source to a coordinate in a field of view defined by at least one of azimuth and elevation, comprises an angled element and a planar reflecting element. The angled element rotates about a first axis and redirects the beam, the redirection of the angled element differing in at least one of direction and extent as it is rotated. The reflecting surface rotates about a second axis parallel to the first. An axis normal to the surface extends at an angle to the second axis. The reflecting surface receives the redirected beam at a point thereon and reflects it in a direction within the FOV. A rotator may be positioned between the source and the angled element to support and independently rotate the angled element and the reflecting surface about the first and second axes without impeding the energy.

摘要： A sensor for determining a profile of an object surface relative to a reference plane comprises a radiation source, a collector, a processor, first and second reflectors and at least one reflective element comprising third and fourth reflectors secured in mutual angular relation. The radiation source projects a launch beam for impingement onto the object surface. The collector detects at least a portion of a return beam reflected by the object surface. The processor determines the profile of the object surface at a point of impingement of the launch beam onto the object surface from at least one characteristic of the at least a portion of the return beam. The first reflector has first and second opposed reflecting surfaces. The first reflecting surface reflects the launch beam along a first path and the second reflecting surface reflects the return beam along a second path parallel to and opposed in direction to the first path. The first reflector is rotatable about a first axis normal to the reference plane, for controlling impingement of the launch beam on the object surface along a second axis parallel to the reference plane and normal to the first axis. The second reflector has a planar reflecting surface for reflecting the launch beam onto the object surface and for reflecting the return beam arriving from the object surface. It is rotatable along the second axis for controlling impingement of the launch beam on the object surface along the first axis. The at least one reflective element is disposed to be impinged upon by the launch beam between the first and second reflectors. The third reflector has a planar reflecting surface for receiving the launch beam after it is reflected off the first reflecting surface of the first reflector and reflecting it onto the fourth reflector. The fourth reflector has a planar reflecting surface for reflecting the launch beam onto the reflecting surface of the second reflector for reflection onto the object surface. In some example embodiments, the at least one reflective element has a refractive boundary, through which the launch beam passes after reflection off the fourth reflector and before reflection onto the object surface that causes the launch beam, if incident on the refractive boundary at an angle to a normal axis of the boundary, to be refracted past the boundary at an increased angle. In some example embodiments, a first end of the third reflector is located proximate to the first axis and the refractive boundary is substantially parallel to the reference plane.

摘要： An apparatus for tracking an object or measuring the range of an object comprises a beam generator for generating first and second beams of energy and projecting the first and second beams towards a target surface whose distance from the apparatus is to be measured, a receiver for receiving energy from the first and second beams reflected from the target surface and for projecting beam energy reflected from the first beam onto a detector for detecting the position of the first beam energy. The position is dependent on the angle between the incident first beam and reflected first beam energy at the target surface, and thereby on the distance between the apparatus and the position from which the first beam is reflected from the surface. A second detector is provided for receiving second beam energy reflected from the target surface for measuring the range of the target by time of flight.

摘要： Methods, systems, devices, and tangible non-transitory computer readable media for haze reduction are provided. The disclosed technology can include generating feature vectors based on an input image including points. The feature vectors can correspond to feature windows associated with features of different portions of the points. Based on the feature vectors and a machine-learned model, a haze thickness map can be generated. The haze thickness map can be associated with an estimate of haze thickness at each of the points. Further, the machine-learned model can estimate haze thickness associated with the features. A refined haze thickness map can be generated based on the haze thickness map and a guided filter. A dehazed image can be generated based on application of the refined haze thickness map to the input image. Furthermore, a color corrected dehazed image can be generated based on performance of color correction operations on the dehazed image.

摘要： An apparatus for measuring the coordinates of a point on the surface of an object comprises a projection system for projecting a beam of energy onto the surface of the object, a receiving system for receiving reflected beam energy from the target surface, and a detector for detecting the received energy. The projection system comprises a beam expander for expanding the width of the beam, and a focussing device for focussing the projected beam. The position of the reflected beam energy at the detector provides a measure of the range of the point on the target surface using triangulation and the direction of the projected beam provides the x and y coordinates. The focussing device can be controlled to vary the focal length of the projected beam and to control the beam size at the target object to vary the area of the target surface illuminated by the beam and thereby to control the resolution of the measurements.
