Research on the new performance model for LLL TV imaging systems

摘要

Starting from threshold characteristics and night visual theory of the human eye the new quanta detector and linear filter integrated performance model, universal threshold detecting theory and synthesis detecting equations for LLL (low light level) TV imaging systems have been put foreword and established, which set up together active regularity and connection between photon noise fluctuation theory and linear filter theory. By using the new performance model and apparent distance detecting equations many specific properties of LLL TV imaging system, such as brightness intensified, visual angle enlarged, signal to noise ratio and contrast transferred and attenuated, can be correctly expressed, calculated and evaluated. The characteristics of the human eye can also be correctly reflected and described.
