Abstract: A system for injection of a useful radiation beam into an optical fiber is disclosed including a secondary radiation source, which is connected to the optical fiber such that a secondary radiation beam leaves by an end of the optical fiber. A variable deviation device, for deviating the useful radiation beam towards the end of the optical fiber, an optical detection assembly, identifying the direction of the secondary radiation beam, and an injection controller, for controlling the variable deviation device depending on the direction of the secondary radiation beam. The secondary radiation may be made up by an amplified spontaneous emission from a laser amplifier which is used for amplifying the useful radiation. The injection system may advantageously be used in a terminal for optical telecommunication by laser signals.

Abstract: A terminal (100) for optical communication by laser signals including a matrix image sensor used as a tracking and acquisition detector (2). The matrix image sensor is used simultaneously to check that a portion of the laser signals received by the terminal are injected into an optical fibre (1). A spectral filter element (22) is associated with the matrix image sensor to allow such a combination of functions.
