Abstract:
1. An imaging device, comprising: a light source; a collimation system to generate a parallel light beam from a beam emitted by the light source; a polarizer to polarize the parallel light beam into polarized light; a rotating optical deflector system to reflect the polarized light into a collimated incident light beam; an optical prism having an apex angle, an entrance face, an exit face and a base provided with a sensitive film, the prism being characterized by its apex angle and by its refractive index; a first afocal optical conjugation system that: a second afocal optical conjugation system that is placed on a side of the exit face of the prism, the second afocal optical conjugation system having a second optical axis, fixed with respect to the prism that is oriented so that, when the collimated incident light beam is parallel to the first optical axis, a second emergent beam parallel to the second optical axis exits the second afocal optical conjugation system; a detection system having a plane sensitive surface that is capable of receiving and analyzing the second emergent beam, the plane sensitive surface being perpendicular to the second optical axis; wherein:
