The Time Delay Integration (TDI) method for blur-free capture of moving images was created in 1973 at Sarnoff. Then known as Image Motion Compensation Mode, this technique sensed charge patterns and shifted them across the charge-coupled device (CCD) array in synch with the movement of the image, to integrate more light from the scene. Over the last three decades, Sarnoff has developed and improved upon this method to create many TDI designs that address demanding client needs.

Utilizing extended dynamic range capabilities and anti-blooming capacity of over 5000:1 — TDI CCDs provide immunity to direct reflections of the sunlight (glints) or specular reflections of lasers while enabling capture of scene detail in both highlight and shadow areas. Other capabilities include high quantum efficiency (QE) and high resolution, as well as wide imaging areas and efficient thermal packaging and management of high-speed circuitry.

TDI provides the technology for low level light capture of moving objects where high output level flash tubes are not available, are too distant, or are insufficient. Examples of such applications are satellite or aerospace imaging, machine vision, or inspection of continuous or web processes. TDI CCDs are also used in applications that require the ability to operate extreme lighting conditions. Solid-state sensors can easily capture images of day and night scenes from weather satellites.
