Imaging Technologies

Electronic imagers and cameras extend the power of human sight. SRI leverages more than five decades of imaging expertise to provide innovative development services and advanced capabilities to clients in many industries.

SRI specializes in the development of high-performance charge-coupled device (CCD) and complementary metal oxide semiconductor (CMOS) image sensors. SRI-designed imagers offer advanced capabilities, ranging from high quantum efficiency and high speed to 100% fill factor and back illumination. Combining novel back-illumination methods and high-speed sensor circuitry, SRI produces unique imagers for the most difficult applications.

SRI meets demanding industrial and scientific sensor requirements in these areas:

  • CCD and electron-multiplying CCD (EMCCD) imagers perform in extreme low-light situations to enhance day- and night-vision systems, including goggles, sights, vehicles, and more

  • Low-light CMOS image sensors for night vision, persistent surveillance, and aerospace applications

  • Scientific imaging solutions for microscopy and biotech applications, as well as DNA sequencing and spectroscopy

  • Time delay integration (TDI) CCD technology enables airborne reconnaissance and satellite imaging, machine vision, and inspection of continuous/web processes
