ABSTRACT:
A large aperture microlens array assembly has at least two arrays of microlenses with individual unit cell trains optically interconnecting individual microlenses in one array with related individual microlenses in another array. In each unit cell train the light entering an entrance pupil of a microlens in one array is transmitted through the exit surface of a related microlens of the other array to provide a collimated output through the exit. One array may be moved with respect to the other array for scanning a field of regard.
