Device for aligning an optical fibre

摘要

In a device for aligning an optical fibre (11) in the direction of a light source (13), the optical fibre (11) is mounted coaxially on a bimetallic element (5) at a distance from the light source (13). The layer (4) of the bimetallic element (5) having the higher coefficient of thermal expansion can be heated via a light-receiving element (7), which is irradiated via the light flux (14) of the optical fibre (11) and downstream of which an amplifier (8) and an electronic control system (9) are connected, and can be aligned with the centre of an aperture stop (15) arranged in front of the light source (13).
