We present the range of optical architectures for imaging systems based on a single optical component, an aperture stop, and a detector. Thanks to the formalism of third-order Seidel aberrations, several strategies of simplification and miniaturization of optical systems are examined. Figures of merit are also introduced to assess the basic optical properties and performance capabilities of suc...

Over the last two decades the use of single-frame interferometric techniques, known as Dynamic Interferometry, have become widely available in commercial interferometer systems and they have been used extensively in the production of state-of-the-art space-based optical systems. This paper presents an overview of the techniques and configurations used to build dynamic interferometers and measur...

A comparison of human gaze patterns on illusions before and after a simple color manipulation is presented. The optical illusions used include Fraser’s illusion, Akiyoshi Kitaoka’s Rotating Snakes, and the Necker cube. All of these images were then modified in an attempt to render the illusion non-illusory. The images are then shown to 8 participants, split into two groups of 4. Each group will...

this article reviews the development of non-invasive optical techniques for determination of blood glucose concentrations in diabetic patients. early diagnosis and daily management are essential for ensuring the healthy life of diabetic patients. the determination of blood glucose concentration with common devices involves the chemical analysis of blood samples, which are obtained by pricking t...

The new optical concepts currently developed in the research field of plasmonics can have significant practical applications for integrated optical device miniaturization as well as for molecular sensing applications. Particularly, these new devices can offer interesting opportunities for optical addressing of quantum systems. In this article, we develop a realistic model able to explore the va...

By introducing a thin ZnO layer as an optical spacer, we have demonstrated that inserting this layer between an active layer and a reflective electrode results in a re-distribution of the optical electric field inside bulk heterojunction solar cells. A theoretical analysis by optical modeling showed that the thin ZnO layer could shift the position of the maximum of the electric field into the a...

Low resolution and narrow viewing angle are common problems for most of the existing autostereoscopic display systems. Although integral imaging is among the promising candidates for future autostereoscopic display, it is not yet free from the above bottlenecks. In this paper, a new technique to enhance the picture quality of a three-dimensional image using an offset lens array is proposed. The...
