About the Cover
The image on the cover for Advanced Photonics Volume 3 Issue 4 depicts a fast-flying butterfly with colorful information on its wings – this dynamic scene is captured by a multidimensional computational camera with super high temporal, volumetric, and spectral resolution. The camera is built based on compressed ultrafast imaging technology, which can simultaneously capture 5D information in a single snapshot by combining compressive sensing with temporal-to-spatial and spectral-to-spatial conversion techniques.
