High-speed transmission over optical fiber connector can be achieved when the optical axes
are completely aligned.
Often several telecameras must be located in the zone of works with different orientation of their optical axes
or the used telecamera must have capability to move in space and to change its orientation.
Collimation: Aligning two optical axes
so they are parallel, or aligning the optical axis of an instrument with its physical axis (as when zeroing a rifle with an optical collimator or checking barrel alignment on a binocular).
The explosion of optical fiber-based infrastructure demands accurate micro-motors and adjustment devices to allow for physical alignment of optical axes
with lasers and fiber-to-fiber connections.
The optical axes
of the emitter and detector are parallel-aligned for optimized reflective operation.
