Abstract
The device has a stabilization mirror that is angularly steerable about two mutually orthogonal axes, and an optical system for splitting an incoming light beam into at least two channels corresponding to different wavelengths. The stabilization mirror is steerable about a first axis (L) on internal equipment that is itself steerable about a second axis (I) orthogonal to the first and intersecting in an assembly that is steerable on a support about a third axis (C). A servo-control system has a gyroscopic sensor tied to the mirror and controlling steering motors. The system further includes, upstream from the stabilization mirror, and on the path of an incoming beam, a purely catoptric optical system that is stabilized, giving the inlet beam a size on the mirror that is smaller than the size of the inlet pupil of the system.
