    Laser remote sensing: yesterday, today and tomorrow
    (НТУУ «КПІ», 2011) Molebny, V. V.; Kamerman, G. W.; Steinvall, O.
    Development of laser remote sensing (lidar techniques) is discussed for atmosphere and ocean investigation. Examples of Raman lidars based on vibrational and rotational energy states of molecular species are demonstrated for remote detection and monitoring of pollution, as well as for studies of dynamics of different components and their parameters. Coherent laser radars allowed remote measurement of speed and vibrations, Doppler velocity information being crucial for the solution of the problem of windshear detection and flight security. A promising trend in laser radar development is incorporation of range and velocity data into the image information. Gated imaging, as one of the 3D techniques, demonstrated its prospects (looking through scattering media, vegetation, dress, etc.) for military and civilian use.

    Recent development of 3D focal plane arrays
    (НТУУ «КПІ», 2011) Kamerman, G. W.
    Laser radars have traditionally employed beam scanning and sequential range interrogation in order to generate three-dimensional (3D) images. Pulsed modulation is commonly used in order to measure range. The image size and image rate of 3D or range imaging laser radars are frequently limited by the pulse repetition rate and by scanner efficiency. Increases in the pulse repetition may increase frame size and frame rate, but only at the expense of increased range ambiguity and increased complexity of the scanner and transmitter. Staring arrays that incorporate time of arrival measurements have recently become available. These arrays have the potential of simplifying instrument design while increasing image size and image rate without increasing range ambiguity. In our work, we discuss most sensitive aspects of ladar design using focal plane arrays.
