Funnel-based biomimetic volume optics

Hybrid Integrated Optics in Volume Holographic Photopolymer

Traditional planar lightwave circuits fabricated from lithographically-patterned waveguides in glasses, semi-conductors or polymers cannot accommodate the wide range of materials required by typical optical devices. In addition, such waveguides are nearly always defined in the material surface and thus can support only a limited density of interconnects and suffer poor performance at waveguide ...

HIGH-VOLUME OPTICS FABRICATION: New technologies enable precise and cost-effective wafer-level optics

Widespread deployment of cameras in consumer products–most noticeably cell phones–has lead to a quest for improved cost efficiency in all manufacturing steps. Wafer-level manufacturing and assembly seems to offer a way forward for cost reduction. Whereas CMOS image sensors are already exclusively manufactured at the wafer level, this is not true for the lens stacks used in consumer cameras. The...

Volume Nano-Structured Optics for 3D Superresolution Imaging

and Introduction: Superresolution microscopy is an imaging technique capable of resolution beyond the diffraction limit [1]. One way to overcome the diffraction limit is by imaging a sparse group of fluorescent molecules so that none or only a few of the neighboring molecules emit photons simultaneously. By repeating this process, an image can then be generated by precisely localizing all the m...

The funnel experiment: The Markov-based SPC approach

The classical funnel experiment was used by Deming to promote the idea of statistical process control (SPC). The popular example illustrates that the implementation of simple feedback rules to stationary processes violates the independence assumption and prevents the implementation of conventional SPC. However, Deming did not indicate how to implement SPC in the presence of such feedback rules....
