A LiDAR sensor comprising: a laser configured to emit a narrow electromagnetic pulse, which is split among a plurality of optical fibers by a fiber cable splitter; a window through which a first split pulse of the narrow electromagnetic pulse emitted by the laser passes, the first split pulse being transmitted by a first one of the plurality of optical fibers; an angular sensor configured to indicate the angular position of the measurement provided by the first split pulse; an electromagnetic pulse receiving sensor configured to receive (i) a calibration pulse obtained by splitting the narrow electromagnetic pulse, the calibration pulse being transmitted by a second one of the plurality of optical fibers, (ii) a first reflected pulse being reflected by the window, and (iii) a second reflected pulse being reflected by an object external from the LiDAR sensor and returning through the window; and a processor configured to: receive information from the angular sensor and the electromagnetic pulse receiving sensor, the information indicating a position of the object relative to the LiDAR sensor; measure an intensity of the calibration pulse from the second optical fiber; measure an intensity of the first reflected pulse being reflected by the window; measure an intensity of the second reflected pulse being reflected by the object; and determine a reflectance property of the object based on the intensity of the calibration pulse, and the intensities of both the first reflected pulse and the second reflected pulse. a laser configured to emit a narrow electromagnetic pulse, which is split among a plurality of optical fibers by a fiber cable splitter; a window through which a first split pulse of the narrow electromagnetic pulse emitted by the laser passes, the first split pulse being transmitted by a first one of the plurality of optical fibers; an angular sensor configured to indicate the angular position of the measurement provided by the first split pulse; an electromagnetic pulse receiving sensor configured to receive (i) a calibration pulse obtained by splitting the narrow electromagnetic pulse, the calibration pulse being transmitted by a second one of the plurality of optical fibers, (ii) a first reflected pulse being reflected by the window, and (iii) a second reflected pulse being reflected by an object external from the LiDAR sensor and returning through the window; and a processor configured to: receive information from the angular sensor and the electromagnetic pulse receiving sensor, the information indicating a position of the object relative to the LiDAR sensor; measure an intensity of the calibration pulse from the second optical fiber; measure an intensity of the first reflected pulse being reflected by the window; measure an intensity of the second reflected pulse being reflected by the object; and determine a reflectance property of the object based on the intensity of the calibration pulse, and the intensities of both the first reflected pulse and the second reflected pulse. receive information from the angular sensor and the electromagnetic pulse receiving sensor, the information indicating a position of the object relative to the LiDAR sensor; measure an intensity of the calibration pulse from the second optical fiber; measure an intensity of the first reflected pulse being reflected by the window; measure an intensity of the second reflected pulse being reflected by the object; and determine a reflectance property of the object based on the intensity of the calibration pulse, and the intensities of both the first reflected pulse and the second reflected pulse.
