Abstract :The basic problem of simulation and modeling of Image Intensified Charge Coupled Device insert ignore into journalissuearticles values(ICCD); is the difference between the analytical Modulation Transfer Function insert ignore into journalissuearticles values(MTF); formulation used in the model and the experimentally obtained MTF. An investigation into the MTF of ICCD sub-components reveal that the MTF of the Image Intensifier Tube insert ignore into journalissuearticles values(IIT); is the main factor in this deviation. In this study, a regulation factor for the MTF of 3rd generation IITs has been developed. A commonly used MTF formulation for IITs has been modified to include a regulation factor which has helped produce more precise MTF values for the Night Vision Sight insert ignore into journalissuearticles values(NVS); device. The results obtained through the new formulation have been compared with the experimental results and it is revealed that the proposed formulation yields MTF values within 3% of the experimental results, on average, while the most commonly used formulation produces approximately 29.5% difference, which amounts to almost 10% improvement in analytical analysis. The analysis is then extended to other generations of IITs where similar improvements have been achieved.
