Summary in English

	The following Doctoral Thesis intends to explain the function of a particular phenomenon, locating the object of study in a certain (given) system, and at the same time, it tries to place the concept of research within the contemporary artistic production. Posed in this manner, the work has a dual function. On one hand, to examine the expansion of the image in a theoretical Ð practical way, explaining why the object of study (the expanded image), the moment it is set to function, creates a particular phenomenon (blinking), that can be apprehended in terms of a constellation. On the other hand, to analyze an approach to the subject of study, which through research, can become an artistic proposal itself. That is, we intend not only to show the reasoning on the chosen subject of study, but to stress the need to refine the concept of research linked to artistic production. The theoretical Ð practical handling of the subject of study turns out to show the characteristics the research may assume within the artistic practice itself, and shows how artists and theorists can reach similar conclusions through different paths, always departing from their own production.
