Our lab is developing miniature Raman imaging systems and topical-staining protocols to rapidly image cell-surface biomarkers in fresh tissues. In particular, this work employs targeted surface-enhanced Raman scattering (SERS) nanoparticles (NPs) to enable the sensitive and multiplexed detection of a large number of cell-surface biomarkers of cancer. The SERS NPs were functionalized with different...
In this paper, figures of merit describing the performances of infrared (IR) bolometer sensor such as thermal response time (τ), responsivity, detectivity (D), noise equivalent power (NEP) and noise equivalent temperature difference (NETD) are estimated using numerical simulations. The proposed model is based on the analytical formulas from Frank Niklaus, et.al. Using this model, we...
This paper presents an imaging Stokes Polari meter attached to a six-axis robot arm with the capability to sense features and structural differences of a sample under test at different incidence-reflection angles. By using Stokes polarization sensing systems more parameters of the reflected light of a sample can be obtained than a conventional imaging analysis. Explanation of the fundamental principles...
