Schematic of THz near-field microscopy based on an air-plasma dynamic aperture. Two femtosecond laser pulses were focused in mutually perpendicular directions to generate two air-plasmas (Plasma1 and ...
a, An axi-symmetric binary phase filter (BPF) and image reconstruction network are jointly learned through the physics-informed neural network. The learned BPF is fabricated and inserted in a pupil ...
Stereo microscopes are often the first choice when high-quality 3D perception of samples is required in the lab or an industrial facility. Users will frequently spend hours looking through the ...
A project at the University of Colorado Boulder (CU Boulder) has developed a new way to image neural activity in live animals. Described in Biomedical Optics Express, the device is a miniaturized ...
