PhoSim simulates the atmosphere, including air turbulence, as well as distortions from the shape of the telescope’s mirrors and the electrical properties of the sensors. The photons are propagated ...

NASA's Hubble Space Telescope captured a bright variable star, V 372 Orionis, and its companion in this festive image in this ...

This paper proposed an image enhancement method that can adapt to changes in turbidity within a certain range. Establishing illumination intensity attenuation model based on light source carried by ...

This work describes a new approach to CMOS Image Sensors (CIS) characterization, based on the Submicron Scanning System (S-cube system). The S-cube system inherently enables two-dimensional ...
