Microlenses for Stereoscopic Image Formation
نویسندگان
چکیده
This paper presents microlenses for integration on a stereoscopic image sensor in CMOS technology for use in biomedical devices. It is intended to provide an image sensor with a stereoscopic vision. An array of microlenses potentiates stereoscopic vision and maximizes the color fidelity. An array of optical filters tuned at the primary colors will enable a multicolor usage. The material selected for fabricating the microlens was the AZ4562 positive photoresist. The reflow method applied to the photoresist allowing the fabrication of microlenses with high reproducibility.

Microlenses array made with AZ4562 photoresist for stereoscopic acquisition
Motivation and results Refractive microlenses arrays have been extensively used in a broad range of applications where focusing or imaging are an appealing alternative for applications where miniaturization and alignment simplicity are requirements [1]. Such microlenses can enhance the light on image sensors (by increasing their sensitivity), on biomedical instruments, on Lab-On-a-Chip systems,...
متن کاملFabrication Methodology of microlenses for stereoscopic imagers using standard CMOS process
This paper presents the fabrication technology of microlenses maintaining a high reproducibility of their characteristics with low cost. The objective of microlenses is to be integrated into imagers in CMOS technology to allow stereoscopic vision. The fabricated microlenses form cylindrical arrays to be placed above the optical filters and photodetectors, in order to potentiate stereoscopic vis...
متن کاملFabrication of two-dimensional arrays of microlenses and their applications in photolithography
This paper describes several methods for the fabrication of microlenses, and demonstrates a lithographic technique that uses a microlens array to pattern the intensity of light incident on photoresist. Three different methods were used to fabricate microlenses: (i) self-assembly of transparent microspheres, (ii) melting and reflow of photoresist on glass substrates and (iii) self-assembly of li...
متن کاملA Doublet Microlens Array for Imaging of Biological Micron-size Objects
We propose a novel fluidic assembly-based microfabrication approach for obtaining low-cost, high numerical aperture (NA), doublet microlens arrays. The proposed doublet architecture consists of glass microspheres trapped on a predefined array of silicon microholes and covered with a thin polymer layer. An array of ~56 μm in diameter microlenses with a numerical aperture of ~0.495 were fabricate...
متن کاملMicrolens arrays
‡Bell Laboratories, Lucent Technologies, 600 Mountain Avenue, Murray Hill, NJ 07974, USA E-mail: [email protected] Microlenses are important optical components that image, detect, and couple light. But most synthetic microlenses have fixed position and shape once they are fabricated, so their possible range of tunability and complexity is rather limited. By comparison, biology provides many...
