Scannig emitter-receiver optical device

摘要

A scanning optical device for emitting and receiving which embodies an optical source adapted to emit a primary beam along an emission axis, a deflecting mirror arranged on an emission axis so as to intercept and deflect the primary beam, a telescope having an optical axis and a detector on this axis, and a scanning mirror mounted so as to rotate around a scan axis coaxial with the optical axis of the telescope and exhibiting a non-zero inclination with respect to the optical axis, wherein the optical source is positioned opposite to the telescope with respect to the scanning mirror, the emission axis being coaxial with the telescope optical axis, the deflecting mirror being fixed to the scanning mirror, and arranged at 90 DEG with respect to the scanning mirror within a central opening provided in the scanning mirror.
