Blur-specific image quality assessment of microscopic hyperspectral images
Hyperspectral (HS) imaging (HSI) expands the number of channels captured within the electromagnetic spectrum with respect to regular imaging. Thus, microscopic HSI can improve cancer diagnosis by automatic classification of cells. However, homogeneous focus is...

Sparse holographic imaging for an integrated augmented reality near-eye display
Diffraction is the main physical effect involved in the imaging process of holographic displays. In the application of near-eye displays, it generates physical limits that constrain the field of view of the devices. In this...

Design of a fast speckle wavemeter with optical processing
We present a design concept for a speckle-based wavemeter that combines high spectral resolution and fast response times. Our device uses a fixed disperse medium with small coherence length as an optical pre-processor and a...

Selecting plasmonic nanoshells for colorimetric sensors
In this work, the use of gold and silver nanoshells was evaluated as a starting point for the establishment of colorimetric sensor platforms. The sensitivity and linearity of the nanoplatforms (SiO 2 core–metallic shell nanoparticles)...
