Abstract (en)
[origin: FR2810416A1] The optical beam pointer has a series of optical inputs (110) and a series of optical outputs (210) and two spatial optical index modulation units (300,400). There is an optically convergent assembly (500) overlapping the first cell focussing the light path onto the second cell and perpendicular to it.
