Convergence of illuminating beams suffering from scattering during the individual measurement of suspended particles

Frontiers in Physics, 2022
The convergent illuminating beam is the key factor during the individual measurement of suspended particles in aquatic suspensions. When the illuminating beam propagates in the suspension, the particle scattering in the optical path may destroy the ...

Metamaterial microbolometers for multi-spectral infrared polarization imaging.

Optics Express, 2022
Vanadium oxide (VOx) microbolometers enable the construction of high-performance yet low-cost and uncooled imaging detectors in the mid-infrared spectrum. Typical micro-bolometers are broadband sensors with no polarization selectivity.

Terahertz polarization imaging

Optics Letters, 2005
We present a new method to measure the polarization state of a terahertz pulse by using a modified electro-optic sampling setup. To illustrate the power of this method, we show two examples in which the knowledge of the polarization of the terahertz pulse is essential for interpreting the results: spectroscopy measurements on polystyrene foam and ...
