Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to unlocking microscopic details inside living cells. Yet despite decades of ...
Scanning near-field optical microscopy (SNOM) offers a means to reach a fine spatial resolution down to ~ 10 nm, but unfortunately suffers from low transmission efficiency of optical signal. Here we ...
ISAMFP concept and system overview. (a) Schematics of beam-scanning, aperture-scanning, and ISA acquisition. (b) Optical layout of the system. (c) Target motion trajectories with recorded frames. (d) ...
Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The approach uses multiple sensors to collect raw light patterns independently, then ...
Large-aperture interferometers are important in the manufacturing and measurement of large-aperture optical elements, which play critical roles in the fields of optical precision manufacturing and ...
Optical measurement systems suffer from a fundamental tradeoff between the field of view (FOV), the resolution and the update rate. A compound eye has the advantages of a wide FOV, high update rate ...
Illustration of Remondo’s partial aperture imaging system, or PAIS. WASHINGTON — An Israeli space startup says it has found a way to extract high-resolution imagery from satellites small enough to fit ...
