摘要： A method for determining a radius of elements suspended in a medium includes binding the elements to nanoparticles to form bound element-nanoparticle aggregates, superposing first and second Doppler-shifted optical waves having a variable frequency shift between them in the medium such that there is a gain in energy of the first optical wave with respect to the second optical wave, varying the frequency shift and measuring the gain while varying the frequency shift to determine the value of the frequency shift at which there is a peak in the gain, determining the radius of the bound element-nanoparticle aggregates based on the value of the frequency shift at which there is a peak in the gain, and determining the radius of the elements based on the radius of the bound element-nanoparticle aggregates.

摘要： Disclosed are security articles and methods and systems for authenticating security articles using a plurality of stimuli. According to one embodiment, an illustrative secured article includes an embedded feature wherein differential activation of phosphorescent or fluorescent materials creates a machine readable response through the simultaneous presence of a source of electromagnetic radiation and a specific gas environment. A detector detects a differential spectral emission across the security feature that results from the change in gas environment. The spectral emission may be compared to an expected emissive signature to determine authenticity of the security article.
