Abstract:
The invention concerns a system for measuring and controlling the wave-front of a coherent light beam (32), comprising: a device for generating a reference light beam (36) that is coherent with said coherent light beam (32); a partially reflective monolithic device (38) comprising an array of elementary cells, each elementary cell comprising at least one element (40) for measuring a portion of the incident wave interfering between the coherent light beam and the reference light beam and a phase modulation element (42) for modulating the phase of the reflected beam; and a control device (46) for controlling said phase modulation element making use of the information from the associated measuring element.
