| Abstract | ||
| 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. | ||
