The Gaze from Nowhere: Lacan and the Optical Unconscious of RF-Sensing Technologies

This paper examines how radio-frequency (RF) sensing technologies transform the structure of surveillance by operating outside the optical register. Whereas photography and film historically expanded visibility and revealed what Benjamin and Kracauer called the “optical unconscious,” RF sensing does not produce images at all. Instead, it registers bodies as patterns of signal reflection within a volumetric field that algorithms translate into actionable events. Such systems generate a “radio-frequency unconscious”: not a hidden layer of the visible, but a nonvisual layer of energetic interactions without appearance or representation that nevertheless yields real clinical, economic, and security consequences. To analyze this shift, the paper rearticulates Lacan’s concept of the gaze. It argues, first, that Lacan’s distinction between eye and gaze provides a productive framework for understanding RF-based sensing; second, that these technologies compel a redefinition of the gaze itself; and third, that this rearticulated notion clarifies why RF sensing cannot be adequately understood through either Foucauldian panopticism or traditional Lacanian visual models. By situating RF sensing within the interplay of the Imaginary, Symbolic, and Real (the three Lacanian psychic registers), the paper shows how surveillance is reorganized when exposure no longer depends on visibility but on signal-based inscription. RF-based sensing restructures space into a field of presences, patterns, and probabilities in which subjects are registered before they can recognize themselves, thereby transforming the conditions under which subjectivity, perception, and surveillance intersect.
