Abstract

The optoelectronical systems with image intensifier tubes (IIT) have today various applications, in different fields: military, industrial or scientific. The variety and complexity of IIT systems applications demand a realistic selection of components and a well-oriented design, on the base of mathematical analysis. This paper presents our theoretical and experimental efforts to find a model for the design of night vision goggles, with the accent to the objective lens, not rarely the most neglected components. We calculate the requested MTF for the objective lens starting from the desired observation range in well establish conditions, the image intensifier tube used in the application and the target configuration. This is possible if were consider the signal to noise ratio as detection criteria in an optoelectronic-generated image. The field and laboratory experiments demonstrate the viability of the theoretical assumptions and relations. In this way, the optical design of this kind of devices may be developed in a controlled way, without useless efforts and costs, with the certitude that the required performances are obtained.
