Abstract
The invention concerns a holographic scanning device that includes: a laser source a rotary body having a rotational geometric axis at least one hologram facet arranged on the rotary body for diffracting a laser beam from the laser source to scan an objective and receive the scattered light from the objective for detection thereof a motor means for driving the rotary body and an optical detector for detecting the scattered light received and diffracted by the hologram facet. The hologram facet is inclined with respect to the rotational geometric axis of the rotary body. (Fig. 4).
