Abstract

In this paper we propose the usage of optical correlation techniques as an analog real-time correlation tracker that can be applicable to solar observations or any other complex image stabilization situation. We present the theory of the VanderLugt and joint extimate filters for optical correlation. Some straightforward scheme of implementation of such devices will be given. Furthermore we will discuss the main advantages for such correlators mainly compared with more traditional digital-based methods.
