ABSTRACT:
The invention relates mainly to a data acquisition device and to a communications system using such a device. The invention provides a device for acquiring data from a light beam, the device comprising an optical system, a first sensor, and a second sensor, wherein at least the two sensors are in successive alignment on a common axis of the beam, the first sensor including, on the axis of the beam, a transparent zone, in particular an opening, that is transparent to at lease a portion of the beam, thereby enabling the second sensor to be illuminated. The invention is mainly applicable to optical communications between satellites, or with a satellite, or to a lidar type device for measuring distance and azimuth, or to implementing homing system.
