    Abstract: A computational ghost imaging apparatus comprising a first electromagnetic radiation source (100) and a control system configured to cause electromagnetic radiation from said first source to be applied to a selected plurality of three-dimensional portions of an atmospheric volume between a second electromagnetic radiation source (110) and object or region of interest (106) so as to heat or ionise the air within said selected portions and create an atmospheric spatial radiation modulator (108) of a specified pattern for causing said object or region of interest to be irradiated with spatially modulated electromagnetic radiation in said specified pattern, the apparatus further comprising a detector for receiving electromagnetic radiation reflected from said object or region of interest (106), and a processing module for reconstructing an image of said object or region of interest using data output by said detector.

    Abstract: Various implementations of the invention compensate for "phase wandering" in tunable laser sources. Phase wandering may negatively impact a performance of a lidar system that employ such laser sources, typically by reducing a coherence length/range of the lidar system, an effective bandwidth of the lidar system, a sensitivity of the lidar system, etc. Some implementations of the invention compensate for phase wandering near the laser source and before the output of the laser is directed toward a target. Some implementations of the invention compensate for phase wandering in the target signal (i.e., the output of the laser that is incident on and reflected back from the target). Some implementations of the invention compensate for phase wandering at the laser source and in the target signal.

    Abstract: A calibration method and a distance measurement device thereof based on phase measurement of a double-wavelength laser tube. The method comprises the following steps: step 1, a first wavelength light-wave is transmitted to a target to be measured through a first light filter from a light wave transmitting device during forming an external light path, the light-wave is modulated from a high frequency oscillating signal (S101); step 2, a second wavelength light-wave is transmitted to the receiving device through a second light filter from the light wave transmitting device during forming an internal light path, as an internal light path signal of a basic reference, the second light-wave is generated from the high frequency oscillating signal (S102); step 3, the receiving device compares phases of the two sequentially received light-waves, and output a phase signal eliminated the base reference (S103).
