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

SRI In the News

SRI's low-light CMOS imaging technology is noted in this round-up of products presented at SPIE's annual Defense, Security and Sensing (DSS) event.

Meal logging and calorie counting is still a pretty painful process, but SRI is working on an image recognition technology that could change that.

According to this article, “’The major change now starting to take place in EO/IR imagery integration is the revolutionary transition from analog I2 tubes to digital low-light CMOS based imager technology,’ said SRI's Tom Vogelsong

This article reports that "with the technology Google has licensed from SRI, image stabilization will no longer be a concern ... at least on Android." Google is implementing the SRI 2D technology in its Google Talk application, to deliver better video on Android 3.0+ devices.

This article reports that SRI recently announced that Google has chosen its 2D video stabilization software for Google Talk on Honeycomb tablets.

This article reports that SRI has recently announced it will be providing image stabilization software to take the jiggles from your future Google Talk videocalls.

According to the article, new technologies are emerging that could help identify someone hiding a gun or crude bomb. "In October, SRI Sarnoff unveiled the camera, which it says can be used to scan crowds for people trying to hide weapons or bombs."
