CMOS The Future of Image Sensor Technology

CMOS imaging is trending to become the dominant imaging technology. Initially, CMOS was limited by its inherent noise. Architectures were then essentially analog and the idea of integrating the image processing features with System On Chip (SoC) technology was yet to be considered. However, it is...

Snapshot High-resolution Hyperspectral Imaging

Traditional digital cameras are comprised of an image sensor, typically either a Charge-Coupled Device (CCD), or, more commonly Complementary Metal-Oxide Semiconductor (CMOS). In either case, these devices integrate an array of photodiodes which convert photons to current which is then integrated...

Round Lens. Square Pixels. Accurate Images. Really?

Alens is cylindrical. It captures light in a circular plane for collection onto a rectangular digital sensor plane. This collection of photons is then transformed into electricity by smaller square pixels. Just how do these disparate shapes work together to provide usable images?

Imaging Detonations of Explosives

An effort has been made within the US Army Research Laboratory (ARL) to extract quantitative information on explosive performance from high-speed imaging of explosions. Explosive fireball surface temperatures are measured using imaging pyrometry (2-color 2-camera imaging pyrometer; full-color single-camera...
