The optical design of miniaturized high resolution micro lens arrays systems
MLAs, for scanning and image formation, is achieved. The types of scanner systems
that have been handled are microlens array MLA scanner system with f-number F#
2.54, for two scanning angles. The one with higher scanning angle predicts the
influence of increasing aberrations on the output. The imaging capabilities of single
and multiple array systems are presented. Their performance characteristics are
studied and analyzed to fit medical applications, the most important are compactness
and resolution. The overall size of the designed systems is a fraction of a centimeter
and the resolution is in a few micrometers regime. However, it is found that
optimizations are needed to enhance the quality of images, specifically for larger
scanning angles.
