Abstract

The system comprises a focusing optics in the focal plane of which a linear array of photodetectors is disposed. A double prism located opposite to said photodetectors with respect to said focusing optics, is servo controlled in rotation relative to a support about its longitudinal axis perpendicular to the axis of said optics, said support being itself servo controlled in rotation about said optical axis in order to scan a space of about 2 π steradians. A derotating prism aligned with said optical axis rotates about said optical axis at a speed half of that of said double prism, in order to hold the image of the target in a single direction in said focal plane, whatever the rotations of said support.
