  • ARRAY OPTICS: Despite challenges, array optics proliferate

    A bundle of 16 to 64 fibers is collimated by a microlens array. The light propagates toward a second microlens array, which is rotating. A dove prism loed midway between the sender and receiver array rotates at half speed and guides each light beam of the static array to its corresponding lens of the rotating array.
