ESTIMATION OF EFFICIENCY OF RADIO FLOW REGISTRATION METHODS AND FORMATION OF SIGNALS OF VARIOUS SPECTRA IMAGES |
T.Yu. Sagdullaev, Yu.S. Sagdullaev
This article shows the features of various methods for recording and converting a radiant flux in spectrozonal television information and measurement systems for generating n-signals of multispectral TV images, where the number of spectral regions used and the number of selected radiant flux recording zones is of paramount importance for optimizing the input optoelectronic link systems and increase the efficiency of spectral selection of objects. The structure of the construction of spectrozonal television systems in which the transmitting TV cameras are implemented using a two-channel optical input circuit using differential, integral differential, or integrated methods for detecting the radiant flux and generating signals of different-spectrum TV images is considered. The effectiveness of various methods for detecting the radiant flux was estimated by two indicators – the potential number of generated signals of different spectral images and the signal-tonoise ratio. The best indicators, according to the possible number of generated signals of different spectral TV images and the signal-to-noise ratio in them, can be achieved by implementing integrated methods for detecting the radiant flux, which can also reduce the requirements for the sensitivity of the MFP by using the registration of the radiant flux in the "wide" spectral region.
Keywords: spectrozonal television, radiant flux conversion methods, differential and integral methods, evaluation of signal generation efficiency, number of generated signals, signal-to-noise ratio.
