Optical Design & Engineering
Miniature droplet lenses for mobile microscopy
Harnessing millimeter-sized liquid droplets enables fabrication of high-power solid lenses of varying focal lengths for use in mobile devices.
Focusing ultrashort laser pulses with achromatic doublets
Spatial-temporal spreading dramatically increases pulse duration and spot size, and decreases pulse intensity.
Simple super-resolution biological imaging
High-index microspheres embedded in elastomer or immersed in liquid allow straightforward super-resolution imaging of biological, metallic, and semiconductor structures.
Watching photons on the fly
Combining a new computational optical imaging method with a streak camera enables 2D ultrafast photography of nonrepetitive events at 100 billion frames per second.
Static real-time capture of 3D microscopy images
Inserting a liquid lens at the aperture stop avoids mechanical movements in widefield microscopy.
Eliminating light leakage in a liquid crystal displayStories 1 - 10 of 80
Using pairs of orthogonal wave plates can eliminate light leakage from liquid crystal displays to allow higher-quality dark images.
