Abstract
An optical system for use in controlling an output radiation pattern includes a microptic multiplet (MOM) optical of first and second micro-lens modules (MLMs) and an array of optical sources. The system is characterized by a first microptic lens module (MLM) that has lenslets of diameter D positioned in substantial registration with alternate ones of the optical sources. The second MLM has its lenslets positioned in substantial registration with a corresponding lenslet in the first MLM at a separation of 2D. The output radiation pattern can be tailored to the specific application.
