Abstract

Disclosed is an imaging device including a light source arranged so as to generate an optical signal, an optical support coupled to the light source and arranged so as to project a luminous excitation signal with a substantially constant light intensity, from the light source to a body to be observed during the use of the device, and an asynchronous camera coupled to the optical support and designed so as to generate a signal including, for each pixel of a first pixel matrix, a signal sequence representing asynchronous events corresponding to variations of the light backscattered by the body to be observed for the pixel.
