Paper Abstract

An important factor in the success of electronic technology in the last few decades is the continuous drive for miniaturization: computing power that used to require a hall full of equipment fits nowadays comfortably in a notebook sized machine. The size of basic optical instruments, however, remained almost unchanged. Today, it is the size of optical devices and subsystems that limits further miniaturization of opto-electronic systems. Here, we describe and demonstrate optical configurations that enable us to design and fabricate very compact optical systems, based on the use of multiple micro-lens arrays. One such system is the multiple lenslet array imager (MLAI) that allows the distance between an object and its full size optical image to be as small as few centimeters, regardless of the size of the object. Another system is the lenslet array holographic correlator/convolver (LAHC), where we combine multiple lenslet arrays and a holographic filter to obtain a very compact optical correlator. Issues in micro-lens arrays fabrication and selected applications are discussed, and some laboratory demonstrations are presented.
