A fraction of a laser beam array, whose unknown piston phase relationships must be set to prescribed values, is launched into a scattering media with random transmission. The resulting output speckle pattern is sampled by an array of photodiodes meas

A phase sensing system fitted to the control of coherent laser beam array of large cross section is experimented. It is based on the use of a fiber bundle that collects a weak part of the synthetic wavefront, that scales it down (1/40) and that resha

A laser beam array, whose phase relationships must be controlled, propagates through a device with random transmission. The resulting speckle pattern provides data to an innovative optimization process leading to efficient and fast phase locking.

The design of 3D printed plastic modular filters is presented in this paper. The proposed principle allows the user to choose at will the order of a bandpass filter by plugging as much blocks (resonators) as needed. The conception and results of a 4-
