Polarization interferometry for real-time spectroscopic plasmonic sensing.
We present quantitative, spectroscopic polarization interferometry phase measurements on plasmonic surfaces for sensing applications. By adding a liquid crystal variable wave plate in our beam path, we are able to measure phase shifts due to small refractive index changes on the sensor surface. By scanning in a quick sequence, our technique is extended to demonstrate real-time measurements. Whi...
متن کاملA spectroscopic refractometer based on plasmonic interferometry
We describe the design, fabrication, and testing of a spectroscopic refractometer that employs plasmonic interferometry to measure the optical dielectric functions of materials in the visible range. The proposed device, dubbed a plasmonic refractometer, consists of an array of slit-groove plasmonic interferometers etched in a 300 nm-thick metal film (silver or gold) with arm lengths varying in ...
متن کاملA “plasmonic cuvette”: dye chemistry coupled to plasmonic interferometry for glucose sensing
A non-invasive method for the detection of glucose is sought by millions of diabetic patients to improve personal management of blood glucose over a lifetime. In this work, the synergistic advantage of combining plasmonic interferometry with an enzyme-driven dye assay yields an optical sensor capable of detecting glucose in saliva with high sensitivity and selectivity. The sensor, coined a “pla...
متن کاملWhite Light Spectral Interferometry for Real-time Surface Profile Measurement
This paper presents a high speed surface profile optical measurement technique based on white light spectral interferometry and parallel signal processing using a general purpose graphic processing unit (GPGPU). A white light source is used to acquire the surface profile of the sample instantly in real time through a cylindrical Michelson interferometer. The interference signals are resolved by...
متن کاملContinuous real-time correction and averaging for frequency comb interferometry.
Interferograms from a dual-comb spectrometer are continuously corrected and averaged in real-time. The algorithm is implemented on a field-programmable gate array (FPGA) development board. The chosen approach and the algorithm are described. Measurements with high signal-to-noise ratio, resolution and bandwidth are shown to demonstrate the accuracy of the optical referencing and the processing ...
