Abstract: A system and method for generating a focused three-dimensional (3D) point cloud is disclosed. A respective 3D point cloud is generated based on returns of a respective sequence of energy pulses that is emitted towards one or more regions-of-interest (ROIs) within a field-of-view (FOV) during a respective scan of the FOV, the returns including one or more secondary returns from one or more points within the FOV. During an additional scan of the FOV, subsequent to the respective scan, an additional sequence of energy pulses is emitted to generate a focused 3D point cloud that includes additional information regarding one or more selected points of the points associated with the secondary returns relative to the respective 3D point cloud.

Abstract: Head mounted displays (HMD) and corresponding display methods are provided, which obtain, repeatedly, from a monitoring system of a vehicle and, a reference vector relating to the vehicle; display on the HMD a reference symbol that indicates the reference vector; and determine movements of a HMD symbology according to a spatial relation between a received user's line of sight (LOS) and the reference vector. For example, the vehicle may be an aircraft and the reference vector a flight path vector (FPV) received from the aircraft's avionics. The proposed HMD enhances the displayed information content while avoiding excessive movements of the symbology. The HMD's functional parameters may be pre-set or adapted according to user preference and flight stage characteristics. The reference symbol anchors most of the symbology, while minimal critical information may be moved along with the user's LOS, providing a clearer and more stable view through the HMD.

Abstract: Aspects of embodiments pertain to a sensing systems configured to receive scene electromagnetic (EM) radiation comprising a first wavelength (WL1) range and a second wavelength (WL2) range. The sensing system comprises at least one spectral filter configured to filter the received scene EM radiation to obtain EM radiation in the WL1 range and the WL2 ranges; and a self-adaptive electromagnetic (EM) energy attenuating structure. The self-adaptive EM energy attenuating structure may comprise material that includes nanosized particles which are configured such that high intensity EM radiation at the WL1 range incident onto a portion of the self-adaptive EM energy attenuating structure causes interband excitation of one or more electron-hole pairs, thereby enabling intraband transition in the portion of the self-adaptive EM energy attenuating structure by EM radiation in the WL2 range.
