Coded aperture imaging (CAI) is an innovative detection method that employs a patterned mask to encode incoming radiation. The encoded signal is subsequently decoded to reconstruct the spatial ...

Pushing for a higher speed isn't just for athletes. Researchers, too, can achieve such feats with their discoveries. A new device called SCARF (for swept-coded aperture real-time femtophotography) can ...

Coded aperture imaging (CAI) is another incoherent imaging technique developed in the 20 th century to achieve lensless 2D imaging with nonvisible wavelengths. In CAI, the light from an object is ...

A high-altitude tactical surveillance system will carry a coded aperture imaging device developed by Qinetiq and Goodrich ISR Systems. The Lacoste Program, from the Defense Advanced Research Projects ...

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 ...
