| Popis: | Results of laboratory experiments on studying the influence of scattering and absorbing media on the quality of object imaging with active pulsed television optoelectronic systems (OESs) are discussed. It is shown that the quality of object images in active pulsed vision systems or their frequency-contrast characteristics can be studied both by direct measurements or indirectly using Fourier transforms of test object images or derivatives of functions determined in experiments. A previously formulated theoretical statement that the image quality for objects screened by turbid media when using active pulsed OESs with backscattered noise signal selection can be higher almost by an order of magnitude than when using an OES operating with laser side illumination and constantly opened receiver has been confirmed experimentally. |
