Description
Summary:Miniature optical components are often manufactured and used in arrays of predetermined pitch. Charge coupled detector arrays, diode laser arrays and modulators such as liquid crystal arrays are familiar examples, often encountered in high-speed applications. The technology is relatively new and standard dimensions are still evolving. To enable arrays with differing pitch to be interfaced, a system that optically converts the pitch of one array to match that of another is desirable. One way of doing this is to use arrays of microlenses, combined to produce a beam steering system based on the Gabor superlens. A simple example that converts an array of 64 beams is described.
