A large amount of data are usually transmitted, stored and processed by big digital systems in satellite remote sensing applications. To alleviate this situation, an on-board data processing system can be of significant help if it allows only the useful information data be transmitted to the ground station. To this end, a new architecture of a LiNbO3 integrated optic pre-processor is proposed in this paper. Its operation is based on the holographic substraction between two incident waves and depends on the relative phase shift. In such a way on-board identification and classification of data are allowed. The proposed device is formed by channel-planar composite waveguides to increase the number of parallel channels. Channel waveguides, which can be excited through a microlens array, allow to obtain the best performance of the electro-optic modulators, each of them is placed on a single channel waveguide, in terms of low losses and high modulation efficiency.
