Hans-Pete Loock – Fiber-Optic Probe for Mercury

Oct 14

What is your idea? In Phase I of the proposed work we will develop an inexpensive fiber-coupled sensor that can detect mercury, Hg(II), in untreated water at levels below 100 ppb and with a response time of < 60 seconds. In Phase II, we will ensure that mercury can be detected in the presence of other common interferences at levels below 50 ppb with an accuracy of 10 ppb, and we will develop...

Zhiwen Liu – Developing a reflection-type G-Fresnel for optical spectrometer miniaturization

Oct 14

What is your idea? Recently we have invented and demonstrated a hybrid diffractive optical element termed G-Fresnel, which integrates the functionalities of a grating and a Fresnel lens in a single thin-film device and can both disperse and focus light. In a typical two-sided realization of this device, a grating and a Fresnel lens are respectively fabricated in the opposing sides of the...

Liang Zhang – Detection System for Early Childhood Caries

Oct 14

What is your idea? We propose to develop an optical device to detect the early onset of tooth decay in young children based on endogenous chromophores. Fluorescence characteristics such as the ratio of multiple fluorescent bands or emission bandwidth may be the “canary” for alerting the medical practitioner to the early stages of tooth demineralization.

Maurizio Tormen – MEMS Wavemeter

Oct 14

What is your idea? Accurate wavelength determination is key for the correct functioning of complex systems, such as in thebiomedical or the construction domain. For example, the stress and deformation inside a building, a bridge or an airplane wing can be detected by using a broadband source, Fiber Bragg Gratings and a wavemeter that detects shifts in the FBGs central wavelengths. In order to...

Scott Rowe – Measuring Macular Pigment: Enabling Preventative Ocular Healthcare

Oct 14

What is your idea? A high amount of macular pigment (MP) improves visual performance, in particular under low contrast conditions, and with intense sources that cause glare. Conversely, low MP densities have been shown to correspond with earlier onsets of Age Related Macular Degeneration, the most prevalent blinding disease of the developed world. Available commercial MP meters use a time...
