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 .pi. 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.

Abstract: Two optical fibers are connected by a device including a base member having a central groove for aligning and abutting the fiber ends. To connect the fibers quickly without having to dismantle any device members, the device comprises a one piece bent spring fastener having a U-shaped cross-section. Natural flexion of a flexible arm of the spring fastener presses the fiber ends into the groove in the immediate vicinity of a fiber endface connection plane. The other arm is anchored to the base member. To connect the fibers, a tool deflects the flexible arm away from the base member and the fiber ends are slide into the groove. The device is in a very slim-like housing and several can be stacked to create a multifiber connecting rack.
