| 英文摘要 | the design and laboratory experiment of a demonstrator of all-optronic down-looking synthetic aperture imaging ladar (sal) is presented in this paper, in which the sensing-to-processing chain is carried out with light. the ultra-fast processing capability from image acquisition to real-time reconstruction is shown. the demonstrator consists of a down-looking sal unit with a beam scanner and an optical processor. the down-looking sal unit has a transmitter of two coaxial orthogonally polarized beams and a receiver of polarization-interference self-heterodyne balanced detection. the linear phase modulation and the quadratic phase history are produced by the projection of movable cylindrical lenses. three functions of strip-map mode, spotlight mode and static mode are available. the optical processor is an astigmatic optical system, which reduces to a fourier transform system and a free-space of the fresnel diffraction to realize the matched filtering. a spatial light modulator is used as the input interface. the experiment is performed with an optical collimator. the system design is given, too. the down-looking sal has the features such as a big coverage with an enhanced receiving aperture and little influence from atmospheric turbulence and the optical processor is simple. |
