    Abstract: Apparatus for mapping includes a radiation source, which is configured to emit a beam of radiation. A first scanning mirror is configured to receive and scan the emitted beam in a first direction over a selected angular range within a region of interest. A detector and optics define a sensing area of the detector. A second scanning mirror is configured to scan the sensing area over the selected angular range in the first direction in synchronization with the scanned beam from the radiation source. A scanner is configured to scan both the emitted beam and the sensing area over the region of interest in a second direction, which is perpendicular to the first direction. A processor is configured to process signals output by the detector in order to construct a three-dimensional (3D) map of an object in the region of interest.

    Abstract translation: 用于映射的装置包括被配置为发射辐射束的辐射源。 第一扫描镜被配置为在感兴趣的区域内的选定的角度范围上沿第一方向接收和扫描发射的光束。 检测器和光学器件限定检测器的感测区域。 第二扫描镜被配置为与来自辐射源的扫描光束同步地扫描在第一方向上的选定角度范围内的感测区域。 扫描器被配置为在垂直于第一方向的第二方向扫描感兴趣区域上的发射光束和感测区域。 处理器被配置为处理由检测器输出的信号，以构建感兴趣区域中的对象的三维（3D）图。

    Abstract: Optical apparatus includes a diffractive optical element (DOE), which includes multiple optical surfaces, including at least an entrance surface and an exit surface, and a side surface, which is not parallel to the optical surfaces of the DOE. A grating is formed on at least one of the optical surfaces so as to receive radiation entering the DOE via the entrance surface and to diffract the radiation into a predefined pattern comprising multiple diffraction orders that exit the DOE via the exit surface. An optical detector is positioned in proximity to the side surface so as to receive and sense an intensity of a high order of the radiation diffracted from the grating that passes through the side surface of the DOE.
