Highly confined surface imaging by solid immersion total internal reflection fluorescence microscopy
Abstract We describe a method that uses total internal reflection at the water–air interface inside large, transparent tank, to measure interface’s deflections. Using this configuration, we obtain an optical set-up where liquid surface acts as deformable mirror. The is shown be extremely sensitive very small disturbances of reflecting water surface, which are detected by means visualising refle...
The radiance structure inside the glass sphere (Figure 1) results from total internal reflection that allows light to reach points that are otherwise in shadow due to refraction perturbing light paths towards the center. The hard boundaries of these structures mark the narrow stripes where light travels around the sphere several times by total internal reflection, after it just managed to enter...
Based on the polarization-sensitive absorption of graphene under conditions of total internal reflection, a novel optical sensor combining graphene and a microfluidic structure was constructed to achieve the sensitive real-time monitoring of refractive indexes. The atomic thickness and strong broadband absorption of graphene cause it to exhibit very different reflectivity for transverse electri...
We propose a new family of achromatic phase shifters for infrared nulling interferometry. These key optical components can be seen as optimized Fresnel rhombs, using the total internal reflection phenomenon, modulated or not. The total internal reflection indeed comes with a phase shift between the polarization components of the incident light. We propose a solution to implement this vectorial ...
