Low-light-level EMCCD color camera

摘要: Video cameras have increased in usefulness military applications over the past four decades. This is a result of many advances technology and because no one portion spectrum reigns supreme under all environmental operating conditions. The visible has clear advantage ease information interpretation, requiring little or training. extends into Near IR (NIR) spectral region to silicon cutoff with difficulty. Inclusion NIR particular importance due rich photon content natural night illumination. addition color capability offers another dimension target/situation discrimination hence highly desirable. A camera must be small, lightweight low power. Limiting resolution sensitivity cannot sacrificed achieve capability. Newly developed electron-multiplication CCD sensors (EMCCDs) open door practical low-light/all-light without an image intensifier. Ball Aerospace & Technologies Corp (BATC) unique that allows very small impact on light level performance negligible limiting resolution. approach, which includes along visible, requires moving parts based sparse sampling filter surface EMCCD. It renders correct hue real time, video rate latency. Furthermore, size power slight.
