Compact microlenslet-array-based magnifier.

Imaging with microlenslet arrays

1. ABSTRACT Recent investigation demonstrated the feasibility of using stacks of microlenslet arrays for optical imaging applications. Many applications driving our research require ultra-compact magnifying imaging systems. In this investigation we demonstrate that a magnifying system based on a stack of two dissimilar microlenslet arrays is feasible. 2. INTRODUCTION Many applications require i...

Design and assessment of microlenslet-array relay optics.

Recent progress in micro-optics fabrication and optical modeling software opens the opportunity to investigate how microlenslet-array-based compact relay systems can be designed and assessed. We present various optical configurations that include an appropriate baffle computation to eliminate ghost images, followed by an analysis of image quality. The investigation shows the existing trade-off ...

Compact Relay Lenses Using Microlenslet Arrays

In an investigation of approaches to compact relay lenses for special effect photography, the potential of microlenslet arrays in image formation is investigated. In this paper, various arrangements of microlenslet arrays and associated baffles are considered and their role on image quality presented. Findings through software simulations clearly demonstrate the trade-offs between image quality...

A New Compact Ultra-wideband Linear Antenna Array for Target Detection Applications

This paper presents a low-cost compact planar microstrip-fed monopole antenna and its four-element array design for ultra-wideband (UWB) wireless communication and target detection applications, respectively, operating in the frequency span of 3 GHz to 11 GHz. A prototype was fabricated and then measured based on optimal parameters. The results of reflection coefficient (S11) and radiation patt...
