Outline of Final Research Achievements |
We have studied an ultra-wideband microwave-modulated laser radar for improvement of the spatial resolution, and performed an experiment of imaging formation of an object. The frequency and the bandwidth are assigned by the Administration of Radio under the Ministry of Internal Affairs and Communications. There is no such limitation in the infrared region. The amplitude modulation in a range of 18GHz is applied to an infrared laser with 1550nm wavelength. There are several benefits using microwave-modulated laser. The speckle is one of the serious problems for obtaining good signal to noise ratio in the microwave region. This problem can be eliminated because an IR laser is used as a carrier wave. The drop of coherence length can also be neglected since the data processing is performed in microwave region. We have succeeded to obtain 3D image of objects by scanning a laser beam in two dimensions and the phase analysis of the reflected waves.
