Introduction to Coded Aperture Spectrometers

This whitepaper is intended to introduce the reader to the Centice coded aperture spectrometer. Here we will explain this form of spectroscopy and show how it fits into the wide array of today’s available spectrometers. This discussion will offer historical perspectives on how and why this form of spectroscopy came to be, and will show that,…..

OPN: Evaluating System Performance – Between a “ROC” and a Hard Place

Published by Optics & Photonic News   How can engineers use a receiver operating characteristics curve to assess the functioning of a complex sensor system?   When Emerson wrote, “Build a better mousetrap, and the world will beat a path to your door,” he likely had no idea how complicated that simply idea could become……

Diffuse Spectroscopy for Inhomogeneous Metal Nanoparticle Assays

ABSTRACT We describe a compact computational spectroscopy platform optimized for molecular recognition using metal nanoparticle assays. The objective is motivated by the urgent need for low-cost, portable and high-throughput sensors for point-of-care (POC) clinical diagnostics. Nanoparticle based sensing has been successfully demonstrated for diagnosis and monitoring of infectious diseases, drug discovery, proteomics, and biological agent…..
