A non-iterative and non-interferometric computational imaging method to reconstruct a complex wave field called synthetic aperture imaging based on Kramers–Kronig relations (KKSAI) is reported. By collecting images through a modified microscope system wit
Amorphous materials are attractive candidates for fabricating the superconducting nanowire single-photon detectors (SNSPDs) due to their superior tolerance and scalability over crystalline niobium nitride. However, the reduced superconducting transition t
The optical system for detecting wake profiles based on laser backscattering by bubbles at 180 degrees is reported, in which the monostatic optical geometry is adopted and the power density estimation is used to process bubble scattering signal. The profi
