16 Facts About CCD sensor

Interline transfer CCD device was proposed by L Walsh and R Dyck at Fairchild in 1973 to reduce smear and eliminate a mechanical shutter.

Subsequently a CCD sensor chip was placed on his tombstone to acknowledge his contribution.

In 1987, the PPD began to be incorporated into most CCD sensor devices, becoming a fixture in consumer electronic video cameras and then digital still cameras.

One other consequence of their sensitivity to infrared is that infrared from remote controls often appears on CCD sensor-based digital cameras or camcorders if they do not have infrared blockers.

Frame transfer CCD sensor imager was the first imaging structure proposed for CCD sensor Imaging by Michael Tompsett at Bell Laboratories.

Frame transfer CCD sensor solves both problems: it has a shielded, not light sensitive, area containing as many cells as the area exposed to light.

Disadvantage of such a CCD sensor is the higher cost: the cell area is basically doubled, and more complex control electronics are needed.

An intensified charge-coupled device is a CCD sensor that is optically connected to an image intensifier that is mounted in front of the CCD sensor.

ICCD sensor cameras are in general somewhat higher in price than EMCCD sensor cameras because they need the expensive image intensifier.

However, high-end EMCCD sensor cameras are equipped with a permanent hermetic vacuum system confining the chip to avoid condensation issues.

However, recent improvements in EMCCD sensor technology have led to a new generation of cameras capable of producing significantly less CIC, higher charge transfer efficiency and an EM gain 5 times higher than what was previously available.

CCD sensor cameras used in astrophotography often require sturdy mounts to cope with vibrations from wind and other sources, along with the tremendous weight of most imaging platforms.

The charges in the CCD sensor are transferred and read in a direction parallel to the motion of the sky, and at the same speed.

Between acquisitions, the CCD sensor is moved in pixel dimensions, so that each point in the visual field is acquired consecutively by elements of the mask that are sensitive to the red, green, and blue components of its color.

The structure of the CCD sensor allows the electrons to flow more easily in one direction than another, resulting in vertical streaking.

Some anti-blooming features that can be built into a CCD sensor reduce its sensitivity to light by using some of the pixel area for a drain structure.
