    Abstract: A DISPLACEMENT DIRECTION AND AMPLITUDE SENSOR A direction and amplitude sensor for detecting displacement comprising a mirror integral with a mobile element and a photoemitter and photoreceptor assembly integral with a reference frame. The assembly comprises a central optical fiber (1) emitting a light cone towards the mirror (10) and optical receiving fibers (2-7). The mirror is circular and its diameter and its axial distance from the extremity of the fibers are such, in centered position, that its diameter substantially corresponds to that of the light cone (11) generated by the central fiber and that the reflected light cone (12) is substantially tangent to the external radial edges of the receiving fibers. The mirror (10) is fitted on the end transversal wall (22) of a tube (21) perpendicularly to the axis of this tube and centered, the other extremity of this tube being embedded in a frame (20), the optical fibers (1-7) having their extremities inside said tube and directed towards the mirror.

    Abstract: The invention concerns a device for transmitting a light beam to zones of a surface, comprising a first mirror (10) arranged in the path of a light beam (11) derived from a first light source (9), directed perpendicularly to said surface (3) and deflecting said beam parallel to said surface; means (13) for pivoting said first mirror along an axis perpendicular to said surface, the rotating beam (14) derived from said second mirror performing a rotary scan; second mirrors (15) distributed around and spaced apart from said first mirror (10), on the path of the light beam (14), and deflecting said beam towards said surface; and means (17) for pivoting said second mirrors (15) along an axis parallel to said surface. By actuating the means pivoting said first mirror (10) and the means pivoting said second mirrors (15), the beams (20) derived from said second mirrors describe beams (22) selectively scanning said zones (2). The invention is useful for heating soldering zones of electronic components.
